The WAV size fields are unsigned 32-bit integers.  Fill them in if
the size would be less than 0xffffffff; otherwise use 0xffffffff to
indicate that the chunk continues until end of file (an unofficial
convention to allow WAV files larger than 4 GiB, when no chunks
follow the audio data).

WAV uses little endian for floats so they must be byte-swapped.

Fixes illumos compiler warning.

If unspecified, lock onto the first plausible port and payload type;
do not mix content for different ports in the same output file.

Allows for automatic checking of arguments.

Adapted from https://github.com/xiph/opus-tools/pull/31, authored
by Muhammad Zaka.

In opusrtp sniff or extract mode, if an output file is specified but
not a payload type, record the first dynamic payload type seen with a
packet that could be a valid Opus packet.

Closes https://github.com/xiph/opus-tools/pull/31

Add -o/--output to specify output file for either sniff or extract
and allow - for stdout.  Allow sniff/extract console output with no
output file (do not default to writing a file with a fixed name).
Use -r/--rate instead of -s/--samplerate for consistency with opusdec.
Clearly indicate in --help which options require an argument.

Use opus_packet_get_nb_samples() instead of our own function, and
warn about packets with an invalid TOC as the timestamp is likely
to be wrong.  Also avoid declarations after statements.

Because it would sleep for the entire packet duration after sending
each packet, the packets would end up too far apart and cause underruns.

Do not depend on usleep() if its POSIX replacements are available.
usleep() was obsoleted in POSIX.1-2001 and removed in POSIX.1-2008.

Make the --extract argument mandatory, as optional arguments don't
work as expected by most people anyway.
Also, now all other parameters are parsed before extraction begins, so
the order of the flags doesn't matter anymore.

Ensure that the request is one that takes an int parameter that can be
overridden safely without the need for special handling in opusenc.
