Remove some dead code from event-loop.c

Browse Source 
This removes some dead code from event-loop.c.

This patch is from my old series to merge the gdb and gdbserver event
loops; but since it is just removing dead code, it seemed simple to
commit it separately.

event can be, for instance, a file descriptor becoming ready to be
read. Servicing an event simply means that the procedure PROC will
be called. We have 2 queues, one for file handlers that we listen
to in the event loop, and one for the file handlers+events that are
ready. The procedure PROC associated with each event is dependant
of the event source. In the case of monitored file descriptors, it
is always the same (handle_file_event). Its duty is to invoke the
handler associated with the file descriptor whose state change
generated the event, plus doing other cleanups and such. In the
case of async signal handlers, it is
invoke_async_signal_handler. */
