143d7f1443 left_block intialisation optimisation. 
This patch changes the left_block initialisation code in the fill_caches

0af6967ee7 chroma_format_idc=0 aka grayscale support. 
Can be disabled by removing #define ALLOW_NOCHROMA in case the extra if()
slow the code down measurably.

af8c5e08d7 Revert r14404 
Remove another 2 incorrect checks.
	These would ignore fields of different parity.
I was wrong, i thought pic_stricture is the current pic structure.
But it does not make a difference either way on the reference bitstreams.

d4f7d83866 Rewrite fill_default_ref_list(), the old code was obfuscated beyond 
repair with hacks.
new code is ~60lines old was ~200
Fixes at least:
FRExt/HCHP2_HHI_A.264
one sample also get decoded much better:
FRExt/FRExt1_Panasonic.avc (PSNR 11 -> 80)
(no i do not know why, the old code was too a big mess to figure out
 what it did)

a82688b003 Setting chroma_qp to 0 for PCM blocks is really an interesting minor 
optimization, more interresting would it have been had the author
thought about what value chroma_qp would have for the following MB.
Or failing that, had actually tested the code.
So this reverts this non-functional optimization, and makes the code work.
