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.
