[PATCHES] Various

[Taylan Ulrich Bayırlı/Kammer]

Here's a series of patches from tracking libva's and VapourSynth's
recursive dependencies.  (They themselves are optional dependencies to
mpv, to whose review-awaiting patch I added them, which shouldn't change
the review result.)

All patches add packages without anything unusual, except for:

- (gnu packages ocrad) renamed to (gnu packages ocr),

- freeglut now propagates mesa.
