From: Thilo Borgmann <thilo.borgmann at mail.de>

Marked WIP because we'd want to introduce private bsf's first; review
welcome before that though
VP8 decoder decoupled again
The whole animated sequence goes into one packet
The (currently public) bitstream filter splits animations up into non-conformant packets
Now with XMP metadata support (as string, like MOV)


Patch 5/8 is still there for making changes in lavc/webp reviewable but shall be stashed when pushing.
