gtk: window sizing overhaul 

Major overhaul for window size handling.  This basically switches qemu
over to use geometry hints for the window manager instead of trying to
get the job done with widget resize requests.  This allows to specify
better what we need and also avoids window resizes.

FIXME: on gtk2 someone overwrites the geometry hints :(
