Eliminate immediate_quit
This finally gets rid of immediate_quit (and surrounding
infrustruture), as nothing sets it anymore.
gdb_call_async_signal_handler was only necessary in order to handle
immediate_quit. We can just call mark_async_signal_handler directly
on all hosts now.
In turn, we can clean up mingw-hdep.c's gdb_select a bit, as
sigint_event / sigint_handler is no longer needed.
