pixdesc: use 8-bit accesses when possible in av_read/write_image_line()

This fixes out of bounds accesses for big endian formats and should be
a little faster.

Rename read/write_line() to av_read/write_image_line().

The old names were not av_ prefixed, and they were causing linking
failure on many platforms. The new names are also more descriptive.

Declare the PIX_FMT_GRAY8 pixel format as a paletted format. This is
consistent with the allocation currently done for PIX_FMT_GRAY8

No significant slow-downs have been measured.

Move read_line() and write_line() definition from pixdesc.h to
pixdesc.c, which are now not anymore marked as static inline.

Fix the inclusion of the private header intreadwrite.h in the public
header pixdesc.h.

H264 DXVA2 implementation

It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.
To compile it, you need to have the system header dxva2api.h (either from...

Make av_pix_fmt_descriptors use the same pixel format names as defined
in libavcodec/imgconvert.c.

Avoid to break compatility when making the functions dealing with
pixel format names in imgconvert.c use the names defined in pixdescs.
