2-3% faster decode on x86-32 core2.

Software decoding was broken since r8865, when two new context variables
were added, but not initialized in vcr2_init_sequence().
Another such context variable was added in r18381.

because YV12 triggers an UV swap in rawdec.c, fixes issue 1687.

Not benchmarked as i failed to find a sample that uses this one. But it should be faster.

Any tips on how i can convince gcc that it doesnt need a
mov     %eax, %eax
in every get_bits() ?

Helps gcc not to add seperate -1 instructions.

Only retry 2 - 5 times in quick succession and afterwards sleep a bit
to avoid creating high CPU load without any progress.

Probably only DoS, init_get_bits sets buffer to NULL, thus causing a
NULL-dereference directly after.

 It allows VLD VC-1/WMV3 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
 It is implemented by using AVHWAccel API.

This should fix a segfault, also it might be faster on systems where the
+52 wasnt free.
