This replaces the explicit offset(reg) memory references with
"m" operands for the same locations.  As a result, one fewer
register operand is needed for these inline asm statements.

When the buf and last pointers are equal, the FFSWAP() results
in an invalid call to memcpy() with same source and destination
on some targets.  Although assigning a struct to itself is valid
C99, gcc does not check for this before calling memcpy().

The existing functions defined in intfloat_readwrite.[ch] are
both slow and incorrect (infinities are not handled).

This introduces a new header with fast, inline conversion
functions using direct union punning assuming an IEEE-754
system, an assumption already made throughout the code.

The one use of Intel/Motorola extended 80-bit format is
replaced by simpler code sufficient under the present
constraints (positive normal values).

The old functions are marked deprecated and retained for
compatibility.

If the sdp is generated before the rtp muxer is initialized
(e.g. as when called from the rtsp muxer), this has to be done,
otherwise the rtp muxer doesn't know that the input really is
in mp4 format.

If an annex b bitstream is muxed into mov, the actual written
sample is reformatted to mp4 syntax before writing.

Currently, the RTP hints that copy data from the normal video
track, where the payload data might be offset compared to the
original sample that the RTP hinting used (when 3 byte
annex b startcodes have been converted into 4 byte mp4 format
startcodes).

Also remove mentions of it from other avtools' manuals.

It's broken and doesn't work anyway.

This patch means that avconv will ignore encoding options from the ffm
file and will instead use whatever is provided on the commandline as for
normal output.

It's not supposed to be set outside of lavc. Set r_frame_rate and
avg_frame_rate instead.

original order is retained within the same tag or codec id to maintain the
muxing/demuxing priority.

This implements reading the tag in the demuxer and adds support for writing it
in the muxer. Some example channel layout tables for muxing are included for
ac3, aac, and alac, but they are not utilized yet.
