Andi McClure a6cf8c5edc [Do not merge yet] Update to mono 2017-04 branch (#1960)
* Update to mono 2017-04 branch

* Patch from Zoltan to fix build error with CppSharp.CppParser.dll

* Include new linker files in Makefile, based on mareks commit

* [msbuild] Fix running bgen for Xamarin.Mac.

bgen must be executed with the system mono, not bmac-mobile-mono, and without
the MONO_PATH variable set.

* System.Data tests should act as if they are running on mobile profile

* Add --runtime=mobile to mono flags in Modern

* Move runtime launcher options up

* System.Data tests should use Mobile profile (mac fix)

* Bump 2017-04 to pick up AOT and assembly resolution fixes

* Build fixes for netstandard.dll and System.Drawing.Primitives.dll

The new handling went in with https://github.com/mono/mono/pull/4501.

I also noticed that WatchOS was missing a target for System.Drawing.Primitives.dll, so I added that.

* Add netstandard.dll to 2.1/Facades and System.Drawing.Primitives.dll to WatchOS

* Fix 2.1/Facades/netstandard.dll build

* Fix the netstandard targets

* Bump mono to latest 2017-04 commit

* [xharness] Fix adding defines to csproj by correctly detecting existing defines.

* Bump mono to latest 2017-04 commit

* [mtouch] Update csproj with new files.

* [mtouch] Improve reporting for MarkExceptions from the linker.

* Bump mono to latest 2017-04 commit

* Bump mono to pick up latest 2017-04 branch commit (Fixes #55436)

Fixes https://bugzilla.xamarin.com/show_bug.cgi?id=55436

* Add a missing Makefile dependency

* Chris Hamons patch to apply --runtime=mobile as necessary at AOT time

(It is currently being applied for some configurations at runtime only)

* Bump system mono

* Bump mono for assembly loader changes

* Bump system mono

* Update assemblies list as some where moved to facades

* Bump mono to latest 2017-04 commit

* Add another new facade

* Bump mono to tip of 2017-04.

* Bump mono to tip of 2017-04.

* [tests][mtouch] Adjust tests to cope with fewer assemblies being included in linked apps. Fixes #56307 and #56308.

System.dll is now completely linked away unless the app actually uses any
System.dll API.

This is the change that caused this to change: 4960d5d2a2

Previously the following types would always be kept by the linker:

```

```

Some of the above types from System.dll implemented ObjCRuntime.INativeObject
(from System.dll), which our linker detected as implementing
ObjCRuntime.INativeObject (from Xamarin.iOS.dll), so these types were treated
as custom NSObject subclasses, and the MarkNSObjects linker step would mark
them (which would in turn cause all the other types in the list to be marked).

With that change, these types now implement ObjCRuntimeInternal.INativeObject,
and the linker does not treat them as custom NSObject subclasses anymore.

I think the new behavior is correct: these types do not actually inherit from
the real NSObject/INativeObject, so the linker should not treat them as such.

This may run into different bugs because the linker might now remove more
stuff than before, but that would be a different issue.

This means that the fix is to modify these tests accordingly.

Q: Why some stuff is not linked out ?

A: In most case this is because:
	a) the BCL uses it internally
	b) the mono runtime depends on the type, methods, class layout


= mscorlib.dll =

System.Security.PermissionSet
	* Assembly has (3) fields of that type
	* mscorlib.xml preserve all fields from Assembly (object-internals.h)
	* code is "stubified" by the linker
System.Security.Policy.ApplicationTrust: 
	* Used as a field in AppDomainSetup;
	* Field also exists in unmanaged code (domain-internals.h);
	* mscorlib.xml preserve all fields from AppDomainSetup
	* only the default .ctor remains and is stubified by the linker
System.Security.Policy.Evidence
	* Used by AppDomain.Load[Assembly]
	* Used by Assembly.LoadWithPartialName overloads
	* code is "stubified" by the linker


= System.dll =

System.Text.RegularExpressions.*
	* Included because there is 2 regex in UriParser
