SRTSOCKET is an abstraction designed by libsrt, it's not guaranteed
to be a real file descriptor. Even if it is, it should not be
operated directly outside of libsrt.

It's useful for test client which pass streamid to ffmpeg/ffplay.
For example, use ffmpeg to test streamid support in VLC:
./ffmpeg -v info -re -i foo.mp4 -c copy -f mpegts -mode listener srt://127.0.0.1:9000
./vlc srt://127.0.0.1:9000?streamid=foobar

When a possible overflow was detected, there was a break to exit the while
loop. However, it should have already substracted 2 bytes from
program_info_length (descriptor ID + length).
Fixes ticket #9422.

The problem was caused by if the width of the processed block
minus 1 is a multiple of the aligned number the instruction
jle .bscale_scalar would skip the Optimized Loop Step, which
will lead to an incorrect sampling when specifying steps more
than 1. Move the Optimized Loop Step after .bscale_scalar to
ensure the loop step is enabled.

This filter chain was supposed to convert from narrow range
to full range yuv444p, but didn't:

time_base=1/25:sar=1/1,zscale=min=709:rin=limited:pin=709:\

Using ff_set_common_formats_from_list() avoids using different functions
depending upon how many inputs the filter has.

The problem here is that the lock ctx->frame_lock will become
an unreleased lock if the program returns at patched lines.

libavformat/utils.c has over 4800 lines and is supposed to contain
"various utility functions for use within FFmpeg". In reality it
contains all that and the whole demuxing core of libavformat.
This is especially bad, because said file includes the FFMPEG_VERSION
(the git commit sha) so that it is rebuilt whenever the commit HEAD
points to changes. Therefore this commit makes it smaller by moving
the demuxing code out to a new file, demux.c (in analogy to mux.c
for the muxing code).

Do this by allocating AVStream together with the data that is
currently in AVStreamInternal; or rather: Put AVStream at the
beginning of a new structure called FFStream (which encompasses
more than just the internal fields and is a proper context in its own
right, hence the name) and remove AVStreamInternal altogether.

This gets rid of ugly "->internal" and is in preparation for removing

The biggest simplifications occured in avformat_alloc_context(), where
one can now simply call avformat_free_context() in case of errors.
