* [registrar] Register models in the static registrar.
This also means we need to quiet a few types of warnings:.
* Models declares virtual methods of required protocol members. We don't
export virtual methods (only when they're overridden are they exported),
which results in numerous warnings about protocol members not being
implemented:

* [AVFoundation] Special-case AVCaptureDataOutputSynchronizer[Delegate] in the registrar for macOS.
This class and protocol were incorrectly added to our macOS bindings, but
since we can't remove them because it would break backwards compatibility, we
must skip them manually in the registrar, since the registrar would otherwise
produce uncompilable code:
In file included from Xamarin.Mac.registrar.full.x86_64.m:2:

* [AVFoundation] Stub out AVCaptureDataOutputSynchronizer[Delegate] on macOS.
AVCaptureDataOutputSynchronizer[Delegate] were incorrectly added to our macOS
bindings, which makes the static registrar's life difficult. So remove those
bindings, and re-implemented them as normal classes, without any attributes,
which makes the static registrar ignore them (to a certain extent: enough to
not generate uncompilable code at least).
* [registrar] Remove more model exclusion code.
* [xtro] Update ignored entries.
You were the preprocessor we wished C# had natively
Removing PMCS requires these changes:
* Remove XamCore from src/
* Remove XamCore from tools/
* Remove XamCore from runtime/
* nint/nuint enum conversion
* _compat_ enum conversion
* NSAction conversion
* Hand fix single API incorrectly converted by PMCS to unbreak compatibility
- Due to a bug in PMCS, the nuint was incorrectly converted in this API.
- However, as that ship as sailed, we must "fix" it until XAMCORE_4_0
* Update readme
* Bump macios-binaries
Converting to and from smart enums and their corresponding native value
requires knowing the conversion function, since each smart enum has its own
conversion function.
The dynamic registrar can do this at runtime, but it's something that can be
computed in the static registrar at build time, so do that. The static
registrar will now embed the metadata token (as a token reference) in the
generated code, which can be used at runtime to find the conversion method,
without requiring anything from dynamic registrar.
This requires some refactoring in the conversion methods to allow passing more
information around (the `context` parameter in the conversion functions, which
the smart enum conversion methods now use for the token reference).
It turns out this is a massive improvement (although the scenarios where this
is relevant are rare): a simple test case [1] is 300x faster (from ~30s to
0.1s).

It seems Apple started shipping CoreNFC headers some time (in a later beta)
after we first implemented (which was Xcode 9 beta 1).
Xcode 9.0, 9.1 and 9.2 all contain the exact same NFC headers (CoreNFC was
introduced with Xcode), so no version checks should be needed when removing
this exclusion.
* [ObjCRuntime] Add a BindingImplAttribute.
* [linker] Make ProviderToString an extension method on ICustomAttributeProvider to make it more discoverable.
* [generator] Use [BindingImpl] instead of [CompilerGenerated].
The entire diff is big (89MB), so it can't be gisted. However, most of it is
either removal of `using System.Runtime.CompilerServices;` or the change from
`[CompilerGenerated]` to `[BindingImpl (...)]` like this:
https://gist.github.com/rolfbjarne/8bfda3ed37b956d0342a1c1e9b079244
If I remove those parts of the diff, there's nothing significant left:
https://gist.github.com/rolfbjarne/4156164d6bdb1376366200394eb8a091
* [linker] Teach the linker about the new [BindingImpl] attribute.
In addition to the existing logic where the linker would optimize some
[CompilerGenerated] code (sometimes with additional requirements), it will now
also optimize all [BindingImpl (Optimizable)] code (without any additional
requirements).
* [tests] Add tests to make sure [BindingImpl (Optimizable)] works as expected.
* [linker] Check for [BindingImpl] before [CompilerGenerated] and stop checking for [CompilerGenerated] in XAMCORE_4_0.
Check for [BindingImpl] before checking for [CompilerGenerated], since the
former is more common.
Also stop checking for [CompilerGenerated] (at least to mean that code is
optimizable) in our next non-compatible evolutionary leap (XAMCORE_4_0):
* [introspection] Impl a better typo check.
The SharedStatic class is a leftover from when there were two static
registrars: the old one (OldStaticRegistrar) and the new one
(StaticRegistrar).
Since there's only one static registrar left (the old one died some time ago),
all the SharedStatic code can be put into the StaticRegistrar class.
There are no functional changes in this PR, only this refactoring.
* [linker] Implement a generic method of storing attributes that may be removed by the linker.
Implement a generic method of storing attributes that may be removed by the
linker, so that those attributes can be accessed after the linker has linked
them away.
* [linker] Store availability attributes using the new generic location.
* [linker] Store the CompilerGenerated attribute using the new generic location.
* [mtouch/mmp] Give users more control over optimizations, and share more code between mtouch and mmp.
1. Add an --optimize flag to mtouch/mmp that allows users to select which
optimizations to apply (or not). This makes it easier to add future
optimizations, and allow users to disable any optimization that causes
problems without having to disable many other features.
2. Share as much optimization code as possible between mtouch and mmp. This
immediately gives a benefit to mmp, which has three new optimizations only
mtouch had: NSObject.IsDirectBinding inlining, IntPtr.Size inlining and
dead code elimination.
This results in ~6kb of disk space saved for a linked Xamarin.Mac app:
* link sdk: [Debug][1], [Release][2]
* link all: [Debug][3], [Release][4]
Testing also verifies that monotouchtest ([Debug][5], [Release][6]) has not
changed size at all, which means that no default optimizations have changed
inadvertedly.

* [tools] Don't enable the IsDirectBinding optimization by default for Xamarin.Mac apps, it's not safe.
* Fix whitespace issues.
* [doc] Document optimizations.
* Officially support optimizations by adding them to the Versions.plist.
* [linker] Improve IntPtr.Size inliner + dead code eliminatior and add tests.
* Properly handle operands for the ldc_i4_s instruction (they're sbyte).
* Fix less-than condition to actually do a less-than comparison.
* Make sure to look up the bitness in the Target, not the Application, since
the Application's value will be incorrect when building fat apps (both
Is32Build and Is64Build will be true).
* Remove unnecessary checks for the IntPtr.Size inliner: this optimization
does not depend on other instructions than the IntPtr.get_Size call, so
remove the checks that verify surrounding instructions. This makes the
IntPtr.Size inliner kick in in more scenarios (such as the new tests).
* Add tests.
* [tests] Add mmp tests for optimizations.
* [tests] Fix XM optimization tests.
* [tests] Fix test build error.
* [runtime] Remove specialized function for getting the Selector/Class handle of a managed Selector/Class instance.
The existing function to get the handle of an INativeObject works just as fine.
* [runtime] Store and use a prebuilt XamMacLauncher.
Some changes in the runtime needs corresponding changes in XamMac.dll, but
since we're not changing XamMac.dll anymore, we can't change the runtime
either.
This means that we must add XamMacLauncher to the list of binaries we copy.
* [runtime] Store and use a prebuilt libxammac*.a as well.
Previous behavior
=================
* The linker would determine if a class is a generated binding class or not.
This was determined by the presence of a constructor taking a single IntPtr
argument, and with a [CompilerGenerated] attribute.
* If a class was not a generated binding class, then that class and all its
superclasses were marked as not optimizable (in the context of inlining the
IsDirectBinding check).
* The end result was that all classes with a [CompilerGenerated] IntPtr
constructor that weren't subclassed, were optimized (the IsDirectBinding
value was implied to be 'true').
Unfortunately this does not match how the IsDirectBinding value is actually
computed, and is in many cases quite wrong.
Background
==========
The authorative value for the IsDirectBinding value is the register attribute:
```csharp
[Register ("MyClass", true)] // the second parameter specifies the IsDirectBinding value
class MyClass : NSObject {}
```
Due to history this second parameter is called `IsWrapper` and not
`IsDirectBinding`, but it's the exact same thing.
Unfortunately looking up this attribute every time a class is instantiated is
slow (since fetching attributes is slow), so we guess this value in NSObject's
initialization: if the actual type of the object is in the platform assembly,
then we assume IsDirectBinding=true:
```csharp
IsDirectBinding = (this.GetType ().Assembly == PlatformAssembly);
```
and any subclasses in the platform assembly which is not a direct binding have
to set the correct value in their constructors.
New behavior
============
In the linker we now track three states for the IsDirectBinding value for each
class: if it can be inlined into a constant true or false, or if it has to be
checked at runtime (a nullable bool is used, and null corresponds with this
last undetermined state).
* The linker will look at the `[Register]` attribute for a class, and:
* If the type is CIFilter, store that IsDirectBinding=undetermined.
* If IsWrapper=False, store that IsDirectBinding=False for that class, and
that IsDirectBinding=undetermined for all super classes where
IsWrapper=True.
* If IsWrapper=True, tentatively assume IsDirectBinding=True in that class
unless already determined to be undetermined (which will be overruled if
a non-wrapper subclass is found later).
Results
=======
For monotouch-test, the changes are as follows:
* Classes we can now assume IsDirectBinding=true: https://gist.github.com/rolfbjarne/acd6a8cf1236562a832d6db9400afee9#file-foo-diff-L1-L25
* Classes we previously assumed incorrectly that IsDirectBinding=true: https://gist.github.com/rolfbjarne/acd6a8cf1236562a832d6db9400afee9#file-foo-diff-L27-L645
* Classes we can now assume IsDirectBinding=false: https://gist.github.com/rolfbjarne/acd6a8cf1236562a832d6db9400afee9#file-foo-diff-L647-L2281
There are also minor size improvements (in the iPhone/Debug64 configuration):
The executable is 17.632 bytes smaller:
-rwxr-xr-x 1 rolf staff 73038384 Jan 12 12:40 /Users/rolf/test/old/monotouchtest.app/monotouchtest
-rwxr-xr-x 1 rolf staff 73020752 Jan 12 12:50 /Users/rolf/test/new/monotouchtest.app/monotouchtest
Xamarin.iOS.dll is 3.072 bytes smaller (this will probably be 0 on a release (stripped) build).
-rw-r--r-- 1 rolf staff 2522624 Jan 12 12:40 /Users/rolf/test/old/monotouchtest.app/Xamarin.iOS.dll
-rw-r--r-- 1 rolf staff 2519552 Jan 12 12:50 /Users/rolf/test/new/monotouchtest.app/Xamarin.iOS.dll
CIFilter
========
There's a complication with CIFilters [1] [2], their implementation is
somewhat special, so we do not want to optimize anything for those classes to
not risk getting anything wrong.

* [mtouch][mmp] Report invalid debug symbols files. Fixes#3200
Try to read the assembly with symbols and, if that fails, warn and
fallback to loading them without symbols.
This fixes cases were it's not easy to update or delete (e.g. nuget)
bad symbols files - so this cannot be an error without causing a lot
of pain.
However it needs to be reported, otherwise it wont be fixed (by the
publisher) and it can limit the debugability of the application and
the usefulness of the stacktraces.
Finally merge most of the resolver's code between mtouch and mmp so
we don't have to fix such issue twice anymore.
note: this needs to be slightly updated once we get a version of cecil
that can give us a more precise error message.

ShouldNotExposeDefaultCtorTest
==============================
This test checks for types with a parameterless ctor that are subclasses
of `NSObject` and then cheks if the BaseType of said objects also expose
a parameterless ctor (all in .NET land), if this is not the case it reports
them and so they can manually audited. Also this test has the ability to
print alloc/init ObjC code by setting `genObjCTestCode` to `true` so you can
take this code into an Xcode project and easily tests the ctors.
It seems that xtro (sharpie) does not have a complete picture of when a ctor
must be exposed hence the hability to generate this code and manually test.
Right now this test is just enabled for MPS since it is the scope of this PR.
In the future it should be enabled for all other frameworks and the output be
manually audited.

The parsing done by `System.Version` does not accept a major-only string,
e.g. providing "11" would throw an exception.
Since people generally refer version as iOS 11 (and not iOS 11.0) this
is, at best, a nuisance. Xcode toolchain accept "11" as a valid string.
The first part of message was updated to show both the option name and
the (user provided) value.
The 2nd part remain the text of the .net exception message, i.e. what
`Version.Parse` tells you when it validates the string. Seeing the input
value should make it more obvious for other, incorrect version strings.

* [mtouch/mmp/bgen] Add support for response files.
This is the first part of the fix for #56501.
https://bugzilla.xamarin.com/show_bug.cgi?id=56501
* [tests] Make sure no single argument starting with a '@' is passed to mtouch unless it's a response file.
--assembly-build-target takes arguments starting with '@', for instance:
--assembly-build-target @all=framework
which does not work anymore, because that's interpreted as a response file
(mtouch tries to read the file '@all=framework', which obviously doesn't
exist).
The fix is simple, don't put a space between the two arguments:
--assembly-build-target=@all=framework
* Add --root-assembly to mtouch/mmp and make the MSBuild tasks use this new option.
This makes it possible to pass root assemblies starting with `@` to mtouch/mmp
without getting mistaken for response files.
* [msbuild] Always use the command-line option that takes an equals or colon.
Always use the command-line option that takes an equals or colon instead of a
space.

--foo=something
--foo:something

so that `something` can start with an at (`@`) sign without being mistaken for
a response file.

The registrar requires the availability attributes to work properly, which is
non-trivial when the linker is being used, because the linker runs before the
registrar, and will remove availability attributes.
For this reason we store the availability attributes separately when the
linker removes them so that the registrar can still find them, but
unfortunately it's not enough to store the CustomAttribute instance, because
it may end up crippled: if the attribute type itself is removed by the linker,
then it's not possible to get the attribute type from the CustomAttribute
instance, because 'attribute.Constructor.DeclaringType' returns null (the
linker sets the declaring type of the constructor to null).
Solution: store the attribute type separately; now we use a Tuple of
CustomAttribute and TypeReference.
Fixes this ugly exception:

This fixes the missing error from bug #59617.

* [registrar] Remove useless interface.
* [registrar] Don't store LinkContext in the static registrar when in can be fetched from the Target. Partially fixes#59617.

* [registrar] Don't verify the SDK for protocol members. Partially fixes#59617.
It's not needed, because protocol members don't end up in the registrar output
anyway (and would thus not prevent the registrar code from compiling).
Classes that implement any protocol members would still run into the SDK
check, so this should not prevent real problematic code from being reported
either.

* [tests][mtouch] Fix tests after registrar changes.
It does not make sense to create Xamarin.iOS projects that don't reference
Xamarin.iOS.dll, so make this an explicit error.
This fixes a NullReferenceException which could (when building for device, or
when not using simlauncher) occur, and instead shows the MT0123 error.

We already have this logic for frameworks we detect according to the namespace
of the used types, but not for frameworks we detect from P/Invokes.
Fix this by using the same framework exclusion logic for frameworks detected
from P/Invokes: don't link with frameworks not available in the current SDK.

Since the native signature doesn't match the managed signature, we need to
manually check the type of each conversion and make sure the required headers
are included.
The two functions mono_class_is_nullable and mono_class_get_nullable_param are
private mono symbols, which means we can't call them when using Xamarin.Mac
with libmono from a dynamic library.
Implement a fallback for this case, where we call a managed method when these
functions are not available (and restrict this workaround to Xamarin.Mac only,
since it's not needed for Xamarin.iOS).
* [mtouch/mmp] Downgrade MT0123 to a verbose log statement instead.
It's unlikely to be useful for normal people who've just set LANG for whatever
unrelated reason.
If it's needed to diagnose failures, it'll still show up in verbose logs.
* [docs] Remove MT0123, it's no longer being used, and we never released a version that used it either.
* [tests][mtouch] Update tests according to code changes (MT0123 removal).
