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.

The encode function is supposed to just return 0 on success.
This stems from a mixup with the return value of decode functions.

This commit fixes a broken build when compiling libavcodec with LLVM
compiler. These assembly files use non-standard format that is only
supported by GCC compiler. It would be nice to use a common standard
format. With this patch, both GCC and LLVM can build and generate the
same objects.

Increase buffer dequeue timeout when the codec needs to be drained as it
could happen that no input buffer is available when we receive a null
packet for the first time (meaning we are unable to signal end of stream
and mark the codec as draining).
Fixes potential loss of last frames after sending a null packet.

Add some more deprecation guards
- psnr() deprecation is not merged within ffmpeg.c as we still use it in
non-deprecated code
- the XVMC chunk is not merged as we still apparently maintain it
- The guarding in lavc/qtrleenc.c could be simplified but merged anyway.
