Uoti Urpala 23cb829072 input: move all key code lists to input/keycodes.h 
Move the definitions of all special key codes (those not passed by
ASCII value) to input/keycodes.h. Before they were spread between
osdep/keycodes.h, input/joystick.h, input/mouse.h and input/ar.h, plus
some special values in input.h. This was especially inconvenient as
the codes had to be coordinated to not conflict between the files.

The change requires a bit of ugliness as appleir.c includes
<linux/input.h> which contains various conflicting KEY_* definitions.
Work around this by adding a special preprocessor variable which can
be used to avoid defining these in keycodes.h.

/*
* General Graphics Interface (GGI) vo driver
*
* copyright (C) 2001 Alex Beregszaszi
*
* Uses libGGI - http://www.ggi-project.org/
*
* TODO:
* * implement gamma handling (VAA isn't obsoleted?)
*
* Thanks to Andreas Beck for his patches.
*
* Many thanks to Atmosfear, he hacked this driver to work with planar
* formats, and he fixed the RGB handling.
