In frame_create, we need to destroy any frame buttons created
in preceding calls to frame_button_create during the function
execution if any of the successive calls to frame_button_create
fail.
This has minimal severity since most, if not all, cases in
frame_button_create that result in a fail (i.e. NULL result) means
a program is OOM and the program will have to exit/abort anyway.

This makes button handling more correct concerning drags. Also,
frame_pointer_button returns the original button location in the case of a
release. This makes filtering of button events much easier for users of
the cair-util frame code.
