vo_gl: add "backend" suboption to allow selecting the GUI backend

Browse Source 
The "backend" suboption allows selecting the GUI backend used by vo_gl.
Normally, it's auto-selected, but sometimes it's desireable to explicitly
select it.

Remove the gl_sdl VO. This can now be done by using: --vo=gl:backend=sdl

This is based on svn commit 34438, and tries to be compatible with it. The
undocumented numeric backend names serve this purpose. (They are
undocumented because names are preferred.)
