7b4367d93e vp9_parser: fix endless loop w/0-sized frame
treat this the same as an over-sized superframe packet to break out of
the parser loop and allow the decoder to fail.

9ee2ddd773 vp9_parse: fix parsing of pskip and profile 2/3.
The fate results change because we now correctly timestamp the pskip
frames, which means the results are now identical to -vsync 0.

a83b6b077c vp9: assign PTS to visible instead of invisible frames
All the webm/vp9 files I have seen so far can have packets that contain
1 invisible and 1 visible frame. The vp9 parser separates them. Since
the invisible frame is always (?) the first sub-packet, the new packet
is assigned the PTS of the original packet, while the packet containing
the visible frame has no PTS.

This patch essentially reassigns the PTS from the invisible to the
visible frame.

09b4ad1568 vp9: avoid infinite loop with broken files
With a certain fuzzed file, the parser will always return 0 consumed
bytes, which makes calling code call the parser infinitely. Return the
full packet size on error instead. (Here it would be nice if parsers
could return errors at all.)

Additionally, _if_ there's some data left, return that too, which might
help with somewhat broken but still somehow playable files.

Fixes ticket .

b88e80589b vp9: fix parser return values in error case
The parser must always set the out_size and out_data pointers. The API
seems to require it, and the common code in parser.c also relies on it.
