Preparatory step to implement support for sizes > VOFW.

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

Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.

Also add support for these formats in libswscale.

Needed for high bit depth h264 decoding.

It is used only for x86 so it will eventually be moved with that code
into the x86 arch subdirectory.

Also add support for these formats in libswscale.

Heres a benchmark

VOFW 5120  VOFW 21504    Note
10438.8    10344.2       timex ffmpeg -y -i tulip2.mp4 tulip2.yuv
25611.9    24256.9       timex ffmpeg -y -itulip2.mp4 -s 1272x724 tulip2.yuv
24485.7    26006.6
28573.1    24291.3
24069.1    26995.9
25684.95   25387.675     average

This is on a Nehalem i7.  Despite being a 500 frame, 720p video, the numbers
fluctuate, so I took an average of 4 runs.

Another reason I'd like this change is youtube accepts videos with higher
resolutions than 5120.
16384 is vp8's maximum resolution, so that should keep us amused for a
little longer.
