This fixes playback of DVB subtitles in
http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket1065/Test1.wtv
in MPlayer.
FFplay is not affected since it assumes that the subtitles
are scaled to match the video - but this usually isn't the
case after rescaling the video and stream-copying subtitles.

This way it won't interfere with WMV9 initialisation inside MSS2 decoder and
avplay will play it fine.

The cpia video decoder is intended to be used with the v4l2 demuxer.
There are some small changes to the v4l2 demuxer to support the
variable frame length of the format.
Fixes ticket #1537

Also, align the mangled RGB planes, which is required for the
SIMD versions of dsputils' median predict.

There is a remaining error of 2 - 8 samples in some but not all cases,
the source of the error is unknown ATM.

The optimized dct_quantize template functions reference optimized
fdct symbols, so these functions must only be enabled if the relevant
optimizations have been enabled by configure.
Using the malloc variant avoids pointless memcpy on size
increase and simplifies handling allocation failure.
Also change code to ensure that allocation, bswap and bitstream
reader all use the same size, even when the packet size is odd
for example.

This fixes building with DEBUG defined after the function was made
static and the prototype removed in d7f9786cbc.

Instead, use it on the first member, since by definition, if
any member is aligned, the whole struct must be, in order to
maintain that alignment.
Fixes compilation with some finicky compilers, like a mix of libclang/msvc

This is a preparatory step for the MSS2 decoder which needs to use
the WMV9 decoder to decode some kinds of frames.

This reverts commit 484a337cd7.
These functions were used in f8bed30 "VC1: merge idct8x8, coeff
