Subject: vo_opengl: move gl_video_opts copying code to separate function

Sigh...

Hopefully this code will be completely unnecessary one day, as it's
only needed due to the sub-option parser craziness.

Move dumb_mode to the top of the struct, so the C universal initializer
doesn't cause warnings with all those broken compilers.
