A few changes are required to have an Application instance at hand when we need to
get the ProductName from it.
This is necessary for .NET, since there will be a single linker library for all platforms,
which means we can't use a constant.
This solves a rebuild problem if an assembly has an invalid or unsupported symbol
file, where we'd detect that the symbol file exists, and expect it to be copied,
but then the linker would drop it, causing us to always rebuild the app (this is
not the same as when a symbol file is out of date).
This happens for NUnitLite 3.12.0's nunit.framework.dll, which ships with an old-style
pdb.
Also add a warning that is shown when we detect that there's a symbol file, but it
couldn't be loaded for some reason.
Add a GatherFrameworksStep that computes the frameworks an app needs, and
returns the result to the MSBuild tasks.
Then we use that list of frameworks to link the native executable correctly.
* Create a simple Xamarin.Utils.Execution class that can handle all our
process execution needs:
* Captures or streams stdout/stderr (in UTF8).
* Supports async
* Supports a timeout
* Does not depend on any other source file we have, only uses BCL API.
* Have the execution helper classes from mtouch/mmp
(Xamarin.BundlerDriver.RunCommand) and the tests
(Xamarin.Tests.ExecutionHelper) use this new class.
* Some simplifications were made:
* All API that took a string array for the environment now takes a
Dictionary<string, string>.
* The Driver.RunCommand methods were split out to a separate file. This
file also contains a Verbosity field, which is conditioned on not being
in mtouch nor mmp, which makes including this file from other projects
simpler (such as bgen - in particular bgen was modified to use this
Verbosity field instead of its own).
Fixes this:
Process exited with code 1, command:
/Users/builder/jenkins/workspace/xamarin-macios-pr-builder/tools/xibuild/xibuild System.Collections.Generic.List`1[System.String]
* Add support for using dotnet instead of msbuild to build the target project.
* cd into the target project's directory before building it, because there may
be a global.json file there which must be taken into account.
* [mtouch/mmp] Share Application.IsDualBuild, Is32Build and Is64Build.
* [mtouch/mmp] Share --tls-provider and --http-message-handler.
* [mtouch/mmp] Share --force.
* [mtouch/mmp] Share --cache.
* [mtouch/mmp] Share --nolink, --linksdkonly, --linkplatform and --linkskip.
* [mtouch/mmp] Share --i18n.
* [mtouch/mmp] Share --xml.
* [mtouch/mmp] Share --registrar and --runregistrar.
* [mtouch/mmp] Share --warn-on-type-ref.
* [mtouch/mmp] Share --sdk.
* [mtouch/mmp] Share --debug.
* [mtouch/mmp] Share --reference, and deprecate -r|--ref and -a|--assembly.
* [mtouch/mmp] Share --targetver, and deprecate mmp's --minos.
* [msbuild] Adjust tests after switching to use --reference instead of -r.
* Update according to review.
* [mmp] Remove --registrar:il.
The IL generator was what MonoMac had before the dynamic/static registrar code
got shared between MonoTouch and MonoMac. The IL registrar been gone for
years, and as far as I know nobody ever used --registrar:il, even though it
was provided as a compatibility option in the beginning (we still had the IL
registrar around for a while after adding the static+dynamic registrars, until
it was completely replaced by the dynamic registrar).
So just remove this option, if anyone ever used it they can replace it with
--registrar:dynamic.
* [mtouch/mmp] Keep bundler-specific code in its corresponding file.
* Move much of ErrorHandler.cs into a partial class in ErrorHandler.tools.cs,
which is referenced by mtouch and mmp (but not our runtime).
* Add ErrorHandler.runtime.cs for runtime-specific bits, including a simpler
version of ErrorHandler.Show. In particular this gets rid of the call to
Environment.Exit, which should never happen at runtime.
* Rename MonoTouchException and MonoMacException to ProductException, which
allows us to remove a lot of ifdefs.
* This required moving Application.LoadSymbols and Target.LoadSymbols to
shared mtouch/mmp code.
That's in /Library/Frameworks/Xamarin.Mac.framework/Versions/Current/SDKs/Xamarin.macOS.sdk/[lib|include]
This allows for a bit more code share between mtouch and mmp.
The native methods xamarin_get_[generic_]method_from_token are a bit unusual
in that they return an actual GCHandle. This is for performance reasons, since
in some cases their return value is passed as parameters to other function
calls to managed code, in which case we need the GCHandle. This way we avoid
round-tripping a GCHandle multiple times.
Not an experiment anymore - it works as expected.
This half-remove the optimization option (it must remain there to avoid
breaking all projects that have it defined) but it will always be `true`
so `Xamarin.Forms.Platform.iOS.dll` will **always** be considered as SDK
code by the linker.

* Rearrange files in Xamarin.Mac a bit to ease code sharing between mmp and
mtouch, by putting mono's static and dynamic libraries in
/Library/Frameworks/Xamarin.Mac.framework/Versions/Current/Sdks/Xamarin.macOS.sdk
to match how Xamarin.iOS does it.
* Don't use 'usr' as an intermediate directory. This removes another special
case.
* Share many of the functions and properties that return specific directories,
and document (as comments) what each function/property is supposed to
return.
Cecil has a fall-back mode where it looks in the GAC / system mono for
assemblies when failing to find them elsewhere. This is not the expected
behavior when using Xamarin.Mac in the Full/XM mode, because then we should
only resolve to assemblies shipped with Xamarin.Mac.
Unfortunately doing so will break apps (our own tests break), so instead
change our resolution to be explicit about where we find assemblies, and if we
find assemblies in the GAC / system mono when we're not supposed to, then show
a warning.
Also add a fall-back mechanism, where we use the old logic instead, in case
the new logic is not 100% compatible with the old one.
This showed up when I tried to port mmp to dotnet, because then Cecil stopped
looking in the GAC / system mono for assemblies (Cecil has a special case when
running on Mono to look in Mono's GAC), and tests started failing.
We're using the Release configuration to build the mtouch and mmp binaries
that we ship, which means that we can use the Debug configuration for
debugging from an IDE, and use the standard conditional compilation symbols to
identify that case.
xcrun can print stuff to stderr even if it succeeds and prints what it found
to stdout, which means we have to separate stdout and stderr when capturing
xcrun's output.
This also means that we need a few changes to our RunCommand API:
* Add support for capturing stdout and stderr separately by providing
different callbacks/StringBuilder instances.
* Use overloads instead of default arguments, because with default arguments
we end up with ambiguous matches in a lot of places with the new overloads.
Fixes https://github.com/xamarin/xamarin-macios/issues/8147.
Backport of #8150.
* [mtouch/mmp] Only use stdout from xcrun as the path of the file that was found. Fixes#8147.

* [tests] Fix mmptest build.
* [mtouch/mmp] Fix process log output.
* Unify target framework code between mtouch and mmp.
* Simplify the code in mmp: have three possible valid target frameworks for
most of code, and add special code to handle setting any other valid target
frameworks to redirect to one of those three valid target frameworks (and
warn if given any of those valid, but not "main", target frameworks). Any
other code can then depend on the target framework having exactly one of
those specific values, which means we can make IsUnified* variables
convenience properties instead.
* Unify a bit more of the argument parsing code between mtouch and mmp, since
that made a few other things easier.
* Add TargetFramework.IsValidFramework to have one validation implementation.
* Move the implementation of TargetFramework.MonoFrameworkDirectory to mmp
itself, it's not really related to the target framework.
* Remove Driver.IsUnified and IsClassic from mmp, they're not used anymore.
* Formally deprecate --xamarin-[full|system]-framework in mmp, they've really been deprecated for many years.
* Remove LinkerOptions.TargetFramework, it's not used anymore.
* Get rid of mmp's userTargetFramework fried, it's duplicated with the
targetFramework field.
* Add a few tests, and tweak others a bit.
Breaking changes:
* Both mtouch and mmp require --target-framework now. The only direct
consumers should be the MSBuild tasks, which already pass --target-framework
all the time. This simplifies code, and removes assumptions.
