Implement signal chaining for windows. Useful for letting custom crash reporters be able to deal with native crashes, without mono eating the native exception while checking to see if it was caused by a managed null dereference in jitted code or not.

	Replace the big lock around the list+array used to queue work items
	with a dynamic concurrent queue to reduce contention.

Prefetch an object's vtable word when it's put on the gray stack,
because it's likely to be scanned soon.

Also prefetch it right before calling the mark/copy function in the
dynamic heap M&S to win a few cycles on the load.  Don't do it for the
fixed heap because there it's unlikely we'll need the vtable anyway,
so the cache can be put to good use elsewhere.

Until now we always loaded the vtable word in the mark/copy function.
It is not necessary in most cases for the fixed heap collector,
however.  If the object is on the small object major heap and its
block size is not evacuated we don't need to load it.

	* threads.c (ves_icall_System_Threading_WaitHandle_WaitAny_internal):
	Store the handles on stack memory.

	* wait.c (WaitForMultipleObjectsEx): Use a stack allocated
	array and detect duplicated by sorting and doing a linear
	search.

The script now supports an extra cross-compilation directory in which you can unpack the
library and development packages necessary for the build to succeed (glib, zlib etc). Also
supported now is specifying the location at which Mono will be installed on Windows.
Replaced SVN and GIT-SVN version checks with git checks.

	* gc.c (finalizer_thread): Clean reference queues
	after finalizers are called to give boehm a chance
	to resurrect it.

By default, Mono now uses an embedded glib implementation, so there
is no need to ship external glib libraries anymore.

These changes are nescessary for compiling with a mingw-w64 compiler.

The macro HAVE_GETPROCESSID is defined in config.h and should not be
exposed in public headers.

Fixed bug #595947. It was complexType [base]-> complexType [base]-> simpleType.

Part of bugfix #595947.

Fixed bug #666333.

Moonlight build: use system tools to compile. This means we don't need a bootstrapping profile either

The file eglib-config.h is generated when running configure.
Distributing eglib-config.h in tarballs causes errors when building
out of the source tree.
