Subject: vo_opengl: add option for caching shaders on disk

Mostly because of ANGLE (sadly).

The implementation became unpleasantly big, but at least it's relatively
self-contained.

I'm not sure to what degree shaders from different drivers are
compatible as in whether a driver would randomly misbehave if it's fed
a binary created by another driver. The useless binayFormat parameter
won't help it, as they can probably easily clash. As usual, OpenGL is
pretty shit here.
