	Based on a patch by Martin Kretzschmar; #122448

	* gdk/gdk.h: new gdk_threads_lock, gdk_threads_unlock, point to
	implementation of GDK_THREADS_ENTER / GDK_THREADS_LEAVE.
	(GDK_THREADS_ENTER, GDK_THREADS_LEAVE): use gdk_threads_[un]lock
	function pointers. Deprecate the global gdk_threads_mutex variable.

	* gdk/gdk.c (gdk_threads_impl_lock, gdk_threads_impl_unlock): new,
	extracted from GTK_THREADS_ENTER/LEAVE macros.
	(gdk_threads_init): init gtk_threads_[un]lock if not set.
	(gdk_threads_set_lock_functions): impl.

	* gdk/gdkglobals.c: add definitions of gdk_threads_[un]lock.

*
* Allows the application to replace the standard method that
* GDK uses to protect its data structures. Normally, GDK
* creates a single #GMutex that is locked by gdk_threads_enter(),
* and released by gdk_threads_leave(); using this function an
* application provides, instead, a function @enter_fn that is
* called by gdk_threads_enter() and a function @leave_fn that is
* called by gdk_threads_leave().
*
* The functions must provide at least same locking functionality
* as the default implementation, but can also do extra application
* specific processing.
*
* As an example, consider an application that has its own recursive
* lock that when held, holds the GTK+ lock as well. When GTK+ unlocks
* the GTK+ lock when entering a recursive main loop, the application
* must temporarily release its lock as well.
*
* Most threaded GTK+ apps won't need to use this method.
*
* This method must be called before gdk_threads_init, and cannot
* be called multiple times.
