Make terminal input work more like VO key input
The Unix version of getch2() could either return an internally buffered
key or do a second-level select() in addition to the input.c one and
then read more data. Change getch2() to always add all read keys with
mplayer_put_key() (like video output window keyboard input does) and
remove the internal select() from the Unix version. Make input.c call
mplayer_get_key() directly.
The primary motivation for this change is to make combining multiple
event sources under one select() easier. Now getch2() only needs to be
called when the corresponding fd is readable, and it will be possible to
handle events from X-based VOs with the same code.
