vo_opengl: cleanup icc + runtime option changing behavior

Commit 026b75e7 actually enabled changing icc options at runtime (via
vo_cmdline), but it didn't quite work. In particular, changing the icc-
profile option just kept the old profile, because it was cached
accordingly.

As part of this, change gl_lcms.opts from a struct to a pointer to a
struct. We properly copy it, instead of allowing possibly dangling
strings, like it was done in a working but unclean way before.

Also, reinit the whole rendering chain when the auto icc profile
changes, just like it's done when icc options are changed.
