* qatar/master:
  swscale: properly inline bits/endianness in yuv2yuvX16inC().
(We didnt pull the bug)  swscale: fix clipping of 9/10bit YUV420P.
  Add av_clip_uintp2() function
(our patch / duplicate)  dfa: fix buffer overflow checks to avoid integer overflows.
(our patch / duplicate)  movenc: always write esds descriptor length using 4 bytes.
(our patch / duplicate)  ffmpeg: use parse_number_and_die() when it makes sense
(No thanks)  ffmpeg: get rid of the 'q' key schizofrenia

udp: add a thread into udp.c for receiving data into a circular buffer, this stops the problem of live decoding/encoding giving errors.

Also added a buf_size which is the number of TS packets that to be allocated for the circular buffer.

Also makes the bpp_tab non static const, as it needs to be changed in
this case.

Fix encoding of monow/monob images, fix trac issue #193.

Reduce code duplication, increase robustness.

Fix decoding of file Test_1bpp.tif, fix trac issue #171.

Helps debugging.

Prefer parse_number_or_die() over atoi()/atol() parsing for the options:
-pass, -top, -vc, and -qscale.

Improve input validation.

swscale changes largely rewritten by me or replaced by baptsites due to lots of bugs in ronalds code.
Above code is also just in case its not obvios to a large extended duplicates that where cherry picked
from ffmpeg.

This allows more 3rd party applications to correctly read
the resulting wav files.

The later parsing of payload data depends on the configuration
being present. If it hasn't been configured properly yet,
parsing a data packet may lead to a crash.

This allows the values to be used without changing C code and is closer to how
the other DEBUG flags work.
