mono_reflection_get_token: For FieldBuilders, now reuse the token
	computed when the FieldBuilder are instantiated, instead of
	re-creating them. This avoids registering field definitions
	as MemberRefs.

	We were previously relying on the runtime to register the token
	for FieldBuilders, but this has issues with fields on generics types
	as it would create a MemberRef token instead of a Field token.

Significant XamlObjectWriter rewrite for solid state transition. And now it supports Array(Extension) and other MarkupExtension types.

Avoid clearing nursery fragments before pinning, instead place arrays at the start of each fragment which cover the whole fragment.

Remove the MonoGenericContext/MonoMethod arguments from the get_this_arg () and get_unbox_trampoline () family of functions, they are no longer needed after the this parameter passing changes.

	This test failed to compile (internal error). Large changes required in
	?mcs before this can be compiled.

	The URL has been moved permanently. Use the raw format instead of
	downloading the HTML page.

	_GNU_SOURCE was redefined

	Use MONO_TYPE_BOOLEAN instead of MONO_NATIVE_BOOLEAN. Same value,
	different enums.

	X509Chain will now add the LM store certificates always, even when the
	CU store is selected.

Use MarkupExtension.ProvideValue() so that XamlObjectReader can return expected Result. Implement internal IXamlNameResolver for Reference resolution.

	* class.c (mono_generic_class_get_class): Don't inflated
	nested_in since it's not the expected behavior from managed
	land. It's a safety issue as well since the outer type can
	have more generic arguments.

	* TypeTest.cs: Add regression test.

	Fixes #643890

Fixes an issue in Process where "pseudo-handles" for processes with
pids > 16 bits would overflow and start getting treated as normal
handles. This would frequently segfault MonoDevelop on MacOS.

When we are not using SHM we use psuedo handles to return processes from pids,
however we dont guard against pseudo-handles in CloseProcess, which could lead to
calling unref on a fake handle.

In a solution file, a Project might not have a corresponding
EndProject. This seems to be supported by VS, so updating xbuild
to support that too. Updated the regex.

	* method-to-ir.c (handle_delegate_ctor): Emit write barriers
	under sgen.

	* method-to-ir.c (mono_method_to_ir): Enable delegate .ctor
	optimization under sgen.

Make the fixed WCF test show more specific failure details.
