Fix how gdb-mi calls display-buffer to avoid switching frames.

Browse source 
* lisp/progmodes/gdb-mi.el (gdb-display-buffer-other-frame-action):
Convert to defcustom.
(gdb-get-source-file): Don't bind pop-up-windows.

* lisp/progmodes/gud.el (gud-display-line): Don't specially re-use
other frames for the gdb-mi case.

Fixes: debbugs:12648
