	Fix a weird race condition which prevented XSP from working inside
	the debugger - see doc/debugger-issues.txt for details.

	* include/gc.h: Moved the "libgc-mono-debugger.h" #include down
	after the gc_pthread_redirects.h one.

	* include/libgc-mono-debugger.h
	(GCThreadFunctions): Added `thread_created' and `thread_exited'.
	(GC_mono_debugger_add_all_threads): New function prototype.

	* pthread_stop_world.c (gc_thread_vtable): Allow the vtable and
	any function in it be NULL; use NULL as the default vtable.
	(GC_mono_debugger_add_all_threads): New public function.

	* pthread_support.c (GC_new_thread): Use calloc() instead of
	GC_INTERNAL_MALLOC() to allocate the `GC_thread' structure.
	(GC_delete_thread): Call `gc_thread_vtable->thread_exited()'.
	(GC_thr_init): Call `gc_thread_vtable->thread_created()'.
	(GC_start_routine_head): Likewise; use calloc() instead of
	GC_INTERNAL_MALLOC() to allocate the `start_info'.
