We don't have a text encoder yet, so this commit makes automatic
encoding working with srt output.

The SRT format should never have outputted CODEC_ID_SRT packets in the
first place: SRT is a subtitle format containing SubRip text markup
events. The timing information is part of the format, not the codec, and
thus CODEC_ID_SRT should not exist.

Creating packets with the timing information within the payload only
leads to problem (such as remuxing with timing alteration not working),
especially when the SubRip markup is being used in container like
Matroska in addition to this standalone SRT format.

The main reason the timing line was included in those CODEC_ID_SRT
packets is likely because it contained extra information (the event
position) the codec actually needs. This issue is solved by using the
AV_PKT_DATA_SUBTITLE_POSITION side data type.

Also fix potential overflow (CID733778)

None of these are likely unless the user is writing a file with two billion
streams or a duration of around two months.

This fixes CIDs 700568, 700569, 700570, 700571, 700572 and 700573.

There's a a potential DoS problem in this function. Say an MXF file is
created with a PixelLayout with a long run of non-zeroes. Such a file could be
sent quickly (packed) over the net and would unpack quite fast. mxfdec would
then read it byte-by-byte, which would take considerable time.

Coverity thinks ofs can end up 15, thus writing past the end of layout[]. This
is incorrect since it's always incremented by 2. Checking ofs <= 14 makes
Coverity happy and doesn't hurt.

This check is somewhat more lenient as would be ideal because we dont
know if the input is signed or unsigned

This adds support for building on Plan 9 x86-32.  The compat/plan9
directory contains these items:

- replacements for the 'head' and 'printf' shell commands
- wrapper for main() to disable FPU exceptions

Larger required changes to the system are described in the
documentation.

The absence of this function will only give a less informative

The libav code depends on mp3 startcodes only occuring at the start of
frames. But there is nothing in mp3 that prevents them occuring elsewhere
by chance. Thus the code would fail randomly, the new code searches for 3
consecutive valid frames. If this turns out to be still insufficient the
number can be raised further, or additional checks added.
