* [registrar] Report a warning when the registrar export an abstract INativeObject type to Objective-C.
Exporting abstract types to Objective-C can lead to problems when at runtime
we're asked to create an instance of such a type (which we can't), so warn
when this happens.
This would have caught #6655, and the problems explained in #4969 as well.
Since this may trigger for code that's currently working fine, I'm making it a
warning instead of an error (which means adding some extra code to be able to
easily report warnings from the generator code).
* Don't assume a TypeReference can be successfully resolved every time.
So far this only applies to `QTKit`...
XM will now, by default, avoid natively link with QTKit unless it's
instructed to so explicitly using `--link-prohibited-frameworks`
ref: https://github.com/xamarin/xamarin-macios/issues/6039
* [runtime] Add an inner exception parameter to Runtime.CreateProductException.
This allows us to simplify code by using inner (and outer) exceptions as
a means to provide information instead of passing extra information
around in order to create decent exceptions.
One example is how we pass the selector and method name to the method
that converts from a native id to a managed NSObject instance: passing
this information is not necessary anymore if we can use two exceptions,
one for the failure to convert from an id to a NSObject instance,
wrapped in a second that tells which method/selector call ran into this
conversion problem.
* [runtime] Throw better exceptions when the dynamic registrar can't marshal something.
* [runtime] Throw a better exception when something goes wrong when trying to marshal a return value.
* [runtime] Use inner exceptions to convey failure information instead of trying to create a single exception with all we know.
* Fix merge problem.
This also centralize other interpreter checks and options in the same
location (making it easier to read / update).
* Warn and switch the REPL if the interpreter is enabled on simulator
Why ? It's confusing to build the same code using different options for
simulator and devices. This is what happens if you try to use features
like `dynamic` or `System.Reflection.Emit`.
So instead of an error, we warn that the interpreter is not supported
and switch to the existing REPL mode.
The JIT remains the only option for the simulator but it allows testing
features without a device.
* Fail early if the interpreter is used on 32bits [1]
The current interpreter only works on 64 bits (so ARM64). However the
error won't be reported, back to the developer, until deployment time.
This temporary [1] fix spot the condition very early and report an error
```
error MT0099 : Internal error : The interpreter is currently only available for 64 bits.
```
instead of the current one at deploy time
```
IncorrectArchitecture: Failed to find matching arch for 32-bit Mach-O input file /private/var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.tNKDlx/extracted/X.app/X
error MT1006: Could not install the application 'X.app' on the device 'Mercure': AMDeviceSecureInstallApplicationBundle returned: 0xe8000087 (kAMDIncorrectArchitectureError).

```

* [tests] Fix/renumbered MT0138
The test was using simulator + interpreter which is not _really_
possible, we use REPL in that case - so we're now checking if
assemblies were specified with `--interpreter` to cover both cases.
Also 0138 was already used by `mmp` and the warning was **not**
registered or documented in the errors documents. To avoid
confusion it has been renumbered to 0142 and documented.
* MachO.cs: Support reading LC_BUILD_VERSION
Newer SDKs set this instead of LC_VERSION_MIN_*
* MachO.cs: Add support for reading Mach-O files inside ar archives.
* [tests] Augment ProductTests.MinOSVersion to test static libraries as well.
* Adjust enum field names to match our naming scheme.
* [linker] Remove non-bitcode compatible code, and show a warning.
Remove code not currently compatible with bitcode and replace it with an
exception instead (otherwise we'll assert at runtime).
Also show a warning when we detect this.
This is quite helpful when looking at watch device test runs to filter out
failures we already know about.
This fixes point #2 in #4763.
* Improve documentation.
* Simplify linker code by using a substep.
* Fix whitespace issues.
* Improve reporting.
* Add support for reporting more than one MT2105 at the same time when making
the errors instead of warnings.
* Only report MT2105 for methods that haven't been linked away.
* Format the error message nicer for properties.
* Tweak a bit for warning tests to pass.
* Use ExceptionalSubStep to provide better error information.
* Adjust where linker warnings/errors are reported from to avoid a NullReferenceException.
* Make PreserveSmartEnumConversionsSubStep use error codes that are not
already used elsewhere: this isn't obvious at first, but all
ExceptionalSubStep errors use a range of error numbers (10 numbers from NNN0
to NNN9), so we need to reserve that entire range. In this case there were
other errors using some of the numbers of the range for PreserveSmartEnumConversionsSubStep.
* Make sure there are anchor links for all the variations of each ExceptionalSubStep error.

Fixesxamarin/xamarin-macios#4107
We currently generate invalid registrar code when we get invalid input
in 'Adopts' attribute, this can happen because 'Adopts' can take a
plain string. We now generate a better error MT4177 instead of
generating invalid registrar.m/h code.
Instead of a generic `MT0000` caused by an exception reading the magic
numbers of the binary framework file.
This was caused be uncompressing an archive, with a symlink, into a
file system that does not support symlinks (on Windows).
ref: https://github.com/xamarin/xamarin-macios/issues/5028
* [runtime] Throw a managed exception instead of trying to call a null function pointer if the runtime tries to call a function that has been linked away.
* [tests] Add new file for Xamarin.Mac tests.
* Direct people to file issues in github.
* Add support for delegates as return values in protocol members. Fixes#4102.
This required a few changes:
* The generator now emits the DelegateProxy attribute for property getters in
protocol interfaces.
* The generator now emits the DelegateProxy attribute in ProtocolMember
attributes (and the ProtocolMember attribute has been extended with
additional properties for this purpose).
* The generator now emits the BlockProxy attribute for the parameter in
property setters.
* The generator now emits the BlockProxy attribute in ProtocolMember
attributes for property setters.
* The static registrar now emits the metadata token for the
DelegateProxy.DelegateType property into the generated code so that the
DelegateProxy attribute itself isn't needed at runtime. This is required
when the dynamic registrar has been optimized away.
Fixes https://github.com/xamarin/xamarin-macios/issues/4102.
* [tests] Update MX4105 test to expect new warnings.
* [mtouch] Show warnings when we can't find referenced assemblies.
This would have helped track down #4235.
* Improve MT0137 warning to indicate the type of the attribute causing the warning.
* Convert it into a MM8027/MT8027 error (with documentation).
* Add information about the selector and managed method that triggered the error.
Now the problem reported in issue #4254 shows up as:
> ObjCRuntime.RuntimeException: Failed to marshal the Objective-C object 0x7f8080412810 (type: UIView). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'UIKit.UIView&' does not have a constructor that takes one IntPtr argument).
> Additional information:
> Selector: popoverController:willRepositionPopoverToRect:inView:
> Method: UIKit.UIPopoverController+_UIPopoverControllerDelegate.WillReposition(UIKit.UIPopoverController, CoreGraphics.CGRect ByRef, UIKit.UIView ByRef)
instead of just:
> ObjCRuntime.RuntimeException: Failed to marshal the Objective-C object 0x7f8080412810 (type: UIView). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'UIKit.UIView&' does not have a constructor that takes one IntPtr argument).
which makes it much easier to understand, track down, and fix/work around,
both for customers and ourselves.
* [mtouch/mmp] Handle invalid types in BlockProxy attributes better. Fixes#4072.
BlockProxy attributes may have types we don't expect, so handle those cases
gracefully by showing a warning when we encounter them:
testApp.cs(11): warning MT4175: The parameter 'completionHandler' in the method 'Issue4072Session.CreateDataTask(Foundation.NSUrl,Foundation.NSUrlSessionResponse)' has an invalid BlockProxy attribute (the type passed to the attribute does not have a 'Create' method).
instead of an ugly MT0000:

The main cause of the warning: "warning MSB6002: The command-line for the 'MTouch' task is too long" was the number of references that can be passed to `mtouch`.
Now all the arguments are written in a response file which in turn is passed to `mtouch`.
- Fixes bug #56501: MSB6002 command-line for MTouch task is too long, > 32000 characters
(https://bugzilla.xamarin.com/show_bug.cgi?id=56501)
- The response file is created in the device specific folder, as `response-file.rsp`. It is re-created every time.
- Added an msbuild test to ensure the response file is created by `GenerateCommandLineCommands` and that it includes all the references.
- Introduce `AddLine` and `AddQuotedLine` which we use to populate the response file (and go to the next line).
- Move to C# 7 syntax for string replacement.
- Update all tests in `MTouchTaskTests` to use the response file since the arguments are no longer passed directly to `mtouch`.
- Update MT0018's documentation for response files.
* [static registrar] Optimize creation of delegates for blocks.

- App Store will now fail builds if you add in a 32-bit dylib
- If you are a 32-bit app you don't need the 64-bit part of your fat
dylib anyway
- Add --optimize=-trim-architectures to allow customization of behavior, as not everyone
uses app store
In addition, while writing tests for this is was noticed that mmp tests did not "really" run Release configuration correctly in most cases. Fixing this turned out to be a bit of a pain, but necessary to correctly test this (and other things).
- Turns out that /p:configuration:debug is not sufficient to tell mmp to
do the right thing
- That, in most projects, sets the DebugSymbols property, which really
is what is checked.
- However, two of our projects did not have that, so we always did
release mmp work.

Generate table of protocols and their corresponding wrapper type in the static
registrar, so that we don't have to look for this information using the

* [linker] Optimize calls to BlockLiteral.SetupBlock to inject the block signature.
Optimize calls to BlockLiteral.SetupBlock[Unsafe] to calculate the block
signature at build time, and inject it into the call site.
This makes block invocations 10-15x faster (I've added tests that asserts at
least an 8x increase).
It's also required in order to be able to remove the dynamic registrar code in
the future (since calculating the block signature at runtime requires the
dynamic registrar).
* [mtouch/mmp] Add support for reporting errors/warnings that point to the code line causing the error/warning.
Add support for reporting errors/warnings that point to the code line causing
the error/warning by adding ErrorHelper overloads that take the exact
instruction to report (previously we defaulted to the first line/instruction
in a method).
* [tests] Add support for asserting filename/linenumber in warning messages.
* Make all methods that manually create BlockLiterals optimizable.
* [tests] Create a BaseOptimizeGeneratedCodeTest test that's included in both XI's and XM's link all test.
* [tests] Add link all test (for both XI and XM) to test the BlockLiteral.SetupBlock optimization.
* [tests] Add mtouch/mmp tests for the BlockLiteral.SetupBlock optimization.
* [tests][linker] Make the base test class abstract, so tests in the base class aren't executed twice.
* [tests][linker] Don't execute linkall-only tests in linksdk.
The optimization tests only apply when the test assembly is linked, and that
only happens in linkall, so exclude those tests in linksdk.
* [tests][mmptest] Update test according to mmp changes.
