	More thorough handling of source indication.  Part of #326041.

	* src/window.c (window_activate): new function based off the old
	meta_window_activate but which also takes source indication into
	account, (meta_window_active): just call window_activate() with
	the necessary source indication to get the behavior wanted,
	(meta_window_client_message): check source indication too for
	_net_active_window messages

	* src/window.h (enum MetaClientType): convenience enum for source
	indication handling
