wm4 e48b21dd87 VO: remove VO direct rendering 
This was disabled by default, and could be enabled with -dr. It was
disabled by default because it was buggy: there were issues with OSD
corruption.

It wasn't entirely sane for OpenGL based VOs either. OpenGL can chose
to drop mapped pixel buffer objects, requiring the application to map
and fill the buffer again. But there was no mechanism in mplayer to
fill the lost buffer again. (It seems this rarely happened in practice,
though.)

On the other side, users liked the --dr flag, because it promised them
more speed. I'm not sure if it actually helped with speed, but it's
unlikely it had any real advantages on modern systems.

In order to evade the --dr cargo culting in mplayer config files, it's
best to get rid of it.
