* changes: Add note about new transient behavior.

	* tests/unixWm.test: Check that the WM_TRANSIENT_FOR
	property for a transient window is being cleared
	when the master is destroyed.
	* tests/wm.test: Source defs.tcl instead of using
	tcltest to match the rest of Tk's test files.
	Add new tests that ensure that a transient's state
	mirrors the state of the master.
	* unix/tkUnixWm.c (WmInfo, TkWmNewWindow, TkWmMapWindow,
	TkWmDeadWindow, Tk_WmCmd, WmWaitMapProc): Add numTransients
	member to WmInfo structure. Keep state of master and
	transient in sync using a callback that tracks MapNotify
	and UnmapNotify events. When the master is mapped, map
	the transient. When the master is unmapped or iconified,
	withdraw the transient.
	* win/tkWinWm.c (TkWmMapWindow, TkpWmSetState,
	TkWmDeadWindow, Tk_WmCmd, WmWaitVisibilityOrMapProc):
	Keep state of master and transient in sync using a
	callback that tracks MapNotify and UnmapNotify events.
	Move masterPtr check from TkpWmSetState into TkWmMapWindow
	to deal with WM_NEVER_MAPPED transients. Cleanup
	numTransients and the callback in TkWmDeadWindow.
	Cleanup numTransients and the callback only after
	deleting a master in wm transient command to avoid
	deleting the callback when an error is raised.
	Add support for MapNotify and UnmapNotify events
	to the master callback.
