[PATCH 6/6] dinput: Use CALLWINDPROC hook to monitor focus loses
away from acquired windows.

This is required for dinput to release mouse and keyboard when foreground
window becomes background. But do this only when coop level is DISCL_FOREGROUND.
To accomplish this set global CALLWINDPROC hook and monitor some messages
sent to windows, associated with acquired DI devices. Because message itself
is not a guarantee that window is not foreground anymore, check this
Also use PostMessage instead of SendMessage in check_dinput_hooks. This
prevents a deadlock, during un-acquire. It should be fine as we don't
have to react immediately to acquire / unacquire.
Window sub-classing won't work if app subclasses the window itself. Also it
makes it complicated to track multiple devices associated with one window
(which is the case most of the time - with keyboard and mouse).
