It can be useful for debugging.

Based on a patch by Stefano Sabatini <stefano.sabatini-lala@poste.it>

This isn't too useful as a normal codec, but can be used in
voip style applications. The decoder updates the noise
generator parameters when a packet is given to it for decoding,
but if called with an empty packet, it generates more noise
according to the last parameters.

This fixes compilation with libswscale disabled.

Plain text (utf8 encoded) data can be muxed and demuxed in nut.

Additionally use the correct error number.

Mainly clean up the RTP statistics code, plus a few other obviously
misindentend lines.

Remove some useless comments, de-doxygenize some comments,
add spacing around operators and fix a typo.

The muxer already rejects unsupported pixel formats, reject also
unsupported codecs to prevent dangerous misuses.

This changes the event_cmp() function to the correct signature,
avoiding an ugly cast.

Subtracting a (positive) value from the address of an array violates
C99 section 6.5.6:

  If both the pointer operand and the result point to elements of the
  same array object, or one past the last element of the array object,
  the evaluation shall not produce an overflow; otherwise, the
  behavior is undefined.

This makes sure the previously always installed public header

This was previously implicitly done in ff_raw_read_header().
Fixes fate tests with pcm input.

avio_size() reports the filesize which returns 0 for /dev/null.
avio_tell() reports the current position.

Also handle errors from avio_tell().

Fixes CID700635, CID700636 and CID732274.

It is not used anymore and is a kludge.
