The volatile qualifiers are not needed on these statements as
their effects are fully specified by constraints.

The flag is required for some C99 math functions to be declared.

Preparatory step to implement support for sizes > VOFW.

This allows to convert between formats of arbitrary width,
regardless of the value of VOF/VOFW.

Many functions have such a prefix, but do not actually use any
instructions or features from that set, thus giving the false
impression that swscale is highly optimized for a particular
system, whereas in reality it is not.

Interleave macros and code so that it's easier to find the
actual code that belongs to a function. Also reindent where
appropriate and remove dead code.

This allows cutting up the function in much smaller and easier-
to-maintain chunks.

If that flag is set, swScale() already proxies the call to
yuv2rgbXinC_full(). Therefore, this flag is never set when
yuv2packed1() is called.

Fixed another dereference in the RTSP code.

Removed a useless variable.

Changed an unnecessary looping assignment to a simple assignment suggested by
Maksym.

Added fixes and tweaks suggested by Maksym Veremeyenko [verem@m1stereo.tv] and
Clément B.

Add a forgotten comma and move options/class definition outside of
HAVE_LIBDC1394_1.

Uninitialized coefficients were being used to generate exponents, some
of which actually ended up in the final stream.  Even though, they were
just extra exponents that are not used by any decoder, it is still
better to have consistent output for testing. This also fixes valgrind
errors.

Having a separate section for audio encoders simplifies navigation
and is slightly more consistent with the rest of the manual.
