  h264: factor out setting the parameter sets for a frame

Michael's changes on top of the merge undo parts of the original diff
that are not factorization:

"The call point is left where it was before. Such a change should be in
a separate commit and has multiple issues, one being null pointer
dereferences the other is that some safety checks would become
conditional.

I tried to split the PPS init between the new and old functions
similarly to the SPS code."

lavc: add mediacodec hwaccel support

h2645_parse: don't overread AnnexB NALs within an avc stream

We know the maximum size of an AnnexB NAL, signaling it as the maximum
NAL size allows ff_h2645_extract_rbsp to determine the correct size.

h2645_parse: only read avc length code at the correct position

Reading it from any other position would result in a wrong size being
read, instead fallback to the re-sync mechanic in the else clause.

lavc/pnm_parser: disable parsing for text based PNMs

P1, P2, and P3 are respectively the text versions of PBM, PGM and PPM
files.

We can not obtain the buffer size using av_imgage_get_buffer_size() as
every pixel in the picture will occupy a random size between 16 and 32
bits ("4 " and "231 " are such example).

Ideally, we could look for the next header (or EOF) in the bytestream,
but this commit is meant to fix a decoding regression introduced by
48ac4532d437790e56b8ed5d0d467dc88685f035.
