Introduce function for directly updating GDB's screen dimensions
... to replace the roundabout pattern of
execute_command ("set width %d");
execute_command ("set height %d");
for doing the same thing.
gdb/ChangeLog:
* utils.h (set_screen_width_and_height): Declare.
* utils.c (set_screen_width_and_height): Define.
* tui/tui-win.c (tui_update_gdb_sizes): Use it.
