Keep only the plain C code in the main rgb2rgb.c and move the x86
specific optimizations to x86/rgb2rgb.c
Change the initialization pattern a little so some of it can be
factorized to behave more like dsputils.

rawdec: fix decoding of QT WRAW files
Fix decoding of QT WRAW files.
From some tests it results that:
1. all of the AVI/MOV WRAW files (at least from the link posted
to the trac ticket #108) need to be flipped
2. mov WRAW files need to use AVI color modes
3. assigning PAL8 mode by default to WRAW codec is not correct
Fix decoding of file CarltonMovie2.mov, fix trac issue #108.

swscale: remove if(bitexact) branch from functions.
Instead, only set the function pointers if bitexact flag is
not set during initialization. Since a change in flags triggers
a re-init anyway, this doesn't situations where flag values
change during runtime.

tiff: set palette in the context when specified in TIFF_PAL tag
Since image initialization was moved after tag parsing, the
palette needs to be specified in the context and then copied
to the allocated image in init_image().

pretending that swscale is highly optimized for AMD3DNOW

ac3enc: add channel coupling support
Channel coupling is an optional AC-3 feature that increases quality by
combining high frequency information from multiple channels into a
single channel. The per-channel high frequency information is sent with
less accuracy in both the frequency and time domains. This allows more
bits to be used for lower frequencies while preserving enough
information to reconstruct the high frequencies.

ffmpeg: Don't trigger url_interrupt_cb on the first signal
Currently, the url_interrupt_cb callback will abort all IO
after the first received signal. This makes the output files
from e.g. the mov muxer to be unreadable if the transcode is
aborted with ctrl+c.
After this patch, the first signal cleanly breaks out of
the transcoding loop, but won't forcibly abort all IO.
After the second signal is received, the url_interrupt_cb
callback will abort all IO.
