This is required if we return other error codes than explicitly
-1, which so far has been the only other possible return value
besides 0.

This replaces a large number of checks for the second field by
fixing the pointers when they are setup.

This should also fix I/BI field pictures.

Changes checksums for vc1_sa10143, the file becomes slightly closer
to what the reference decoder outputs.

Based on "vc1dec: the second field is written wrong to the picture"

Also eliminate an unnecessary cast. Fixes the following warning:
jpeg2000dec.c:1200:20: warning: format ‘%lX’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘long long unsigned int’

Fixes read of uninitialized memory.

This was due to a miscomputation of s->cur_channel, which led to
psy-based encoders using the psy coefficients for the wrong channel.

This fixes a case where multichannel bitrate isn't accurately
targetted by psy model alone, never achieving the target bitrate.

The header is not (anymore) MMX-specific.

Also remove some pointless comments.

The goal is to make the capapility slightly more general and have it
cover the availability of the nopl instruction in addition to cmov.

Cells starting at a position aligned to 8 pixels but wider than
4 blocks are copied with 3 blocks per loop. This creates problems on the
next loop iterations since the routine copying 2 blocks requires the
same alignment on some architectures like ARM NEON.

From 253 to 51 cycles on Arrandale and Win64.
44 cycles on SandyBridge.
