Previously the assumption was that if an assembly not using dlsym references a
native symbol, it's not a required symbol. This is true as far as the native
linker goes: the native linker will see that the native symbol is referenced
by the AOT-compiled code, and it won't be removed.
However, we use also this exact logic to create the list of functions we ask
the native strip command to preserve, and in this case we need to include all
symbols needed in all assemblies that looks up native functions using dlsym.

Some Quote implementations quoted backslashes, some didn't. When selecting a
common implementation, one of the implementations that didn't quote
backslashes won, and the rest were forgotten. Almost. Except for the MT0106
test, which started failing, thus exposing the winner's deficiencies.
So dethrone the implementation that won and reinstante the importance of the
backslash.

HFS normalizes filenames to Form D when files are stored. This means that an
assembly whose assembly name is stored in Form C might be stored in a file
whose filename is Form D (which you'll get if you use the Form C filename).
However, this is a problem when we've already loaded an assembly and if we
doesn't take normalization into account: we check the cache based on the
filename, but store in the cache based on the assembly name. If those two uses
different normalization schemes, bad things (bug #57266) happen.
So in these scenarios normalize strings before comparing them.

* [mtouch] Improve how we make sure native symbols aren't stripped away. Fixes#51710 and #54417.
* Refactor required symbol collection to store more information about each
symbol (field, function, Objective-C class), and in general make the code
more straight forward.
* Implement support for generating source code that references these symbols,
and do this whenever we can't ask the native linker to keep these symbols
(when using bitcode). Additionally make it possible to do this manually, so
that the source code can be generated for non-bitcode platforms too (which
is useful if the number of symbols is enormous, in which case we might
surpass the maximum command-line length).
* Also make it possible to completely ignore native symbols, or ignore them on
a per-symbol basis. This provides a fallback for users if we get something
right and we try to preserve something that shouldn't be preserved (for
instance if it doesn't exist), and the user ends up with unfixable linker
errors.
* Don't collect Objective-C classes unless they're in an assembly with
LinkWith attributes. We don't need to preserve Objective-C classes in any
other circumstances.
* Implement everything for both Xamarin.iOS and Xamarin.Mac, and share the
code between them.
* Remove previous workaround for bug #51710, since it's no longer needed.
* Add tests.

* [mtouch] Make sure to only keep symbols from the current app when code sharing.
This fixes a build problem with the interdependent-binding-projects test when
testing in Today Extension mode.
This change introduces the export of create_classes methods as objc compatible, without enforcing Objective-C++ as the development language for custom registrar embedders by moving the stringbuilder flushing inside the extern "C" block.
Mark the generated linking code as extern "C" too and also change the return type of xamarin_create_classes_Xamarin_Mac to void in mmp generation, as it was mistakenly set to int.
The AVFoundation framework's headers used to be broken in the simulator SDK
([1], [2]) until watchOS 3.2 (Xcode 8.3) fixed it. This means it's now safe to
use AVFoundation.
Additionally set the initial SDK version where this framework was introduced
to 3.2 for simulator builds, which means that if customers try to use it (with
an old Xcode), they will get a nice-ish error:
> MTOUCH : error MT4134: Your application is using the 'AVFoundation' framework, which isn't included in the watchOS SDK you're using to build your app (this framework was introduced in watchOS 3.2, while you're building with the watchOS 3.1 SDK.) Please select a newer SDK in your app's watchOS Build options.
instead of an ugly:
> MTOUCH : error MT4109: Failed to compile the generated registrar code. Please file a bug report at http://bugzilla.xamarin.com
the error message is slightly incorrect (the problem is only with the
simulator SDK, not the device SDK), but this should happen very rarely (it
only occurs if all of the following are true: using AVFoundation + in a
simulator build * the static registrar manually selected), so IMHO a more
accurate error description isn't worth it.

* [registrar] Add support for specifying that a protocol changed informal status in a certain SDK. Fixes#43780
Add support for specifying that an informal protocol became a formal protocol
(or the reverse) in a certain SDK version, so that the static registrar can
generate the correct code based on the SDK being built with.
This also fixes a series of compiler warnings when using the static registrar:

* [registrar] Use a string to specify when a protocol went from informal to formal.
Use a string to specify when a protocol went from informal to formal, and
don't support the reverse condition (going from formal to informal), since
it's currently not needed and makes the code more complicated and harder to
understand.
Also add an mtouch test, and update an existing mmp test to be more restrictive.
* [registrar] Rename from 'InformalUntil' to 'FormalSince'.
It just sounds better.
This avoids the following compiler warning:

I found the magic symbol by looking at the headers.
If both an extension and the container app (or multiple extensions) reference
the same binding assembly for a framework, then we'd error out with an
internal error when trying to copy the framework from both locations to the
container app.
So instead detect when we're trying to copy multiple identical (by comparing
the on-disk contents) frameworks, and only copy one of them.
We'll still show an error if the frameworks are different, but now a nice
MT1035 error with a proper error description instead of an internal error.

[registrar] Support 'out' parameters from NULL pointers. Fixes#54919.
Native code doesn't have the 'out' and 'ref' distinction C# has, and passes
NULL around left and right.
So make sure the generated code from the static registrar doesn't write to such NULLs.

Replace https://github.com/xamarin/xamarin-macios/pull/1973 expect that
the test parts are still needed.
* Add XM SDK + LinkSkip test
* [macos] Add platform linking support to msbuild
* [macos] Add full SDK test
* [macios] Diable classic from using linkplatform
- Extended test infrastructure change to allow classic projects that include bundling
- Setting linkplatform in MonoBundlingExtraArgs since we don't even read project setting LinkMode - Platform for classic
This makes registrar.h compilable as Objective-C (as opposed to
Objective-C++), because the __monoObjectGCHandle field (whose type is an C++
type) isn't there anymore.
When gathering frameworks, gather into the product assembly's frameworks, not
the global frameworks.
This is necessary when building a non-linked dylib/framework in embeddor mode,
because we link the registrar code into the framework, and that code will
require linking with all the frameworks all the assemblies require.
- Before this mmp was not adding -framework, -weak_framework consistently on non-static registrar use cases
- GatherFrameworks was previously not ported from mtouch, and did not work as DeploymentTarget was unset in mmp
- Added verbose prints so users can determine why various framework linkages are added
- Fixed an issue where duplicate were being added due to HandleFramework shoving args by hand
- Tested with auto test and https://github.com/chamons/xm-version-regression-test manual test
This fixes a file sharing exception:
> MTOUCH: error MT1009: Could not copy the assembly '[...]/msbuild/tests/MyActionExtension/bin/iPhone/Debug/MyActionExtension.dll' to '[...]/msbuild/tests/MyTabbedApplication/obj/iPhone/Debug/mtouch-cache/32/Link/MyActionExtension.dll': Sharing violation on path [...]/msbuild/tests/MyActionExtension/bin/iPhone/Debug/MyActionExtension.pdb
A fix (thanks Rolf!) in how we do SDK version checks is needed
because for some reason `new Version (3, 2, 0)` isn't the same to
`new Version (3, 2)` and we end up with a MT4134 when building the
watchOS static registrar.
