Submodule referencesource removal - #2962

This will let us have both the Mono and the Microsoft ThreadPool at the same time.
To switch to the Microsoft one, set the MONO_THREADPOOL environment variable to "microsoft". It will default to the Mono one.

Confirmed by Brett Lopez as MSDN bug

DISABLE_CAS_USE is required to avoid NotImplementedExceptions in CAS land.

MONO_HYBRID_XML is to preserve Mono's XmlSerializer which also allows
interpreter-based XML serialization (as opposed to run-time code generation
based XML serialization, which is not doable in iOS).

Though some Xml.Serialization classes are useful even with mono
implementation, so we partially import them (namely schema importer).

Somewhere in System.Xml requires NameTable to be canonically reused when
deserializing XmlSchema, so that certain deserialization part can check
only reference equality.

Since we have hybrid System.Xml implementation for XmlSerializer, this
is not completely achieved and with reference comparison it causes some
schema deserialization failure. To avoid this problem, just disable
reference comparison. It should not affect outside XmlSchema serialization.

…ilds.

The former condition is to disable <msxsl:script> element.
The latter is to disable XslCompiledTransform and co (though they are
mostly removed at *.dll.sources level).

Should fix bug #27258.

… of which breaks build"

This reverts commit 0cb499950a7ae61c62c433c8cce353d535dbd09e.

GetHRForLastWin32Error breaks the build on AOT, and even on non-AOT is unimplemented.

NativeMethods.GetExitCodeProcess would inherently be broken on Unix platforms for non-child processes as it can't succesfully get the exit code. This would in turn break Process.HasExited, which should not break, as it is possible to check if a non-child process is alive or dead.

…e22, it was eaten up by the .NET 4.6 merge. Fixes #38712

In case the runtime would fail to wait on the wait handle(s), we would still return true, as if the WaitHandle was successfully signaled.

When FileInfo was imported in mono@bdd0de7 the check in Delete()
got removed that raised an UnauthorizedAccessException when the FileInfo object holds a path to a directory instead of a file.

It happened to pass the MonoTests.System.IO.FileInfoTest.Delete_Directory test on OSX because unlink returns EPERM there
which got turned into the expected UnauthorizedAccessException, but on Linux it returns EISDIR so the test would fail.

Fix is to put the explicit check for directory back.
