	* glib/gwin32.c
	(g_win32_get_package_installation_directory_of_module): New
	function. Supersedes g_win32_get_package_installation_directory()
	and g_win32_get_package_installation_directory().

	It makes more sense to have the function for this functionality
	take a HMODULE as parameter instead of DLL name. The typical use
	scenario has been to have a DllMain() function that retrieves the
	full pathname for the DLL in question, and saves just the basename
	of that. Then later code passes that saved dll basename to
	g_win32_get_package_installation_directory(), which retrieves the
	corresponding DLL handle, and then retrieves up its full
	pathname. (Which DLlMain() already had.) It is less convoluted to
	have a DllMain() that just saves the DLL handle, and then when
	needed call this function to get the corresponding installation
	folder.

	(get_package_directory_from_module): Use
	g_win32_get_package_installation_directory_of_module().

	(g_win32_get_package_installation_directory)
	(g_win32_get_package_installation_subdirectory): Mention these
	functions will be deprecated and recommend using
	g_win32_get_package_installation_directory_of_module() instead.
	
	* glib/gwin32.h: Declare
	g_win32_get_package_installation_directory_of_module().

	* glib/glib.symbols: Add it.
