vo_opengl: minor renderer option access refactor

Reduce accesses to the renderer opts in vo_opengl.c, and instead add
accessors for them to video.c.

I suppose gamma and maybe icc-auto could be moved to vo_opengl.c
options. Also, the output colorspace could probably be adjusted to what
is really used, not just the options (although it's possible that this
commit changes this, due to video.c mutating its own copy of the options
according to actual renderer capapbilities).

But don't deal with this now.
