Having a string callback is much more simpler than a variable args
one for writers to deal with, especially when dealing with escaping.

This patch also introduces a local fast_asprintf() function which is
similar to av_asprintf() but avoids reallocating at each print (leading
to a performance issue).

I dont know on which system the prior check failed but an advanced
linker on some platform might have optimized func() out as unreachable.

This makes it rememember old values should the stream not
contain new values for these for each subtitle.

This fixes overwriting x264 preset settings for flags2 based options.

This avoid retrying to read ASF index in files for every
attempt to seek. This makes a big difference to protocols
with slow seeking (for example http)

This fixes https://ffmpeg.org/trac/ffmpeg/ticket/448 - at least for
rc_lookahead. A similar problem still exists for the flags2 based
options.

Also consistent with AVCodecContext.sample_rate. Simplify/avoid
pointless type checks and conversions.

Breaks audio API/ABI.

The additional parameters were never used and are complicating the
function interface. Also, they were inconsistent with the way the
video API works.

So this assumes that a requested samples buffer will have *always* the
format specified in the requested link.

This breaks audio filtering API and ABI.

mxfdec: skip to end of structural sets This fixes reading of partition packs. The code stops reading after the operational pattern and should skip the array of essence container labels that follow

Ignore another filetype, as generated by Microsofts lib.exe when creating the import libraries.

Move shared tables to a separate file as well.

This prevents some crashes when corrupted bitstream reports e.g. P-type
slice in I-frame. Official RealVideo decoder demands all slices to be
of the same type too.
