This is much faster with slow shells and noticeably faster even
with bash on a fast Linux system.

This way, SIMD-optimized functions don't have to sign-extend their
stride argument manually to be able to do pointer arithmetic.

Replace INIT_AVX by INIT_XMM avx. Port the whole file to use cpuflag
based function declarations. Remove (now unused) cputype argument in
function declaration macros. Change function prototypes to have mmx2
instead of mmxext as suffix, since that's required by cpuflags.

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.

This gets rid of this warning:

libavformat/rtsp.c: In function ‘rtsp_parse_transport’:

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.

Indexing across array boundaries is not allowed by C99.

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.

HAVE_THREADS is set in config.h if pthreads or w32threads is
available, which presumably the proper condition here.

This avoids Doxygen believing the attribute is the function name.
