[MPlayer-dev-eng] [PATCH] add "xbutton" support to vo_directx

[Joey Parrish]

Hello,

This patch adds "xbutton" support to vo_directx.  These are the 4 or 5
button mice with buttons on the sides which Microsoft assigns to "back"
and "forward" for IE.  These two buttons will show up as 5 and 6 in
MPlayer's input layer.

These button events will only happen on win2k or winxp, but the code
should compile and run on 95 & 98 still.

Ok to commit?
