Remove static mpctx from mplayer.c

Pass it in function calls instead. There's no reasonable way to pass
it to exit_player() when used outside mplayer.c. However most of those
uses seem to be wrong (the code should not make the program exit) and
should be removed. For now just make exit_player() uses outside
mplayer.c simply call exit() without any shutdown code.
