aac2c12663 add quantizer adaptive intra mb mode encoding
make intra mode coding entropy distribution adaptive to baseQindex, an
encoding test on hd clips with all key frame shows universal gain on
all clips in both .2%(psnr) and (ssim).3%.

To build and test, configure with
--enable-experimental --enable-qimode

ca6b85aa4e add 8x8 intra prediction modes
Patch 1 to Patch 3 is an initial implementation of 8x8 intra prediction
modes, here are with the following assumptions:
a. 8x8 has 4 prediction modes DC, H, V and TM
b. UV 4x4 block use the same mode as corresponding 8x8 area
c. i8x8 modes are enabled for key frame only for now
Patch 4:
d. removed debug code from previous patches
Patch 5:
e. added stats code to collect entropy stats and further cleaned up
Patch 6:
f. changed mode stats code to collect finer stats of modes
Patch 7:
g. normalized i8x8 modes distribution to total at 256 (8bits).
Patch 8:
h. fixed a bug in decoder and removed debug printf output.
Patch 9:
i. more cleanups to address paul's comment
Patch 10:
j. messy rebase/merges to bring the commit up to date.

Tests on HD clips encoded with all key frame showing consistent gain
on all clips and all metrics:~0.5%(psnr) and 0.6%(ssim):

1741cc7ab9 Reverse coding order for segment features:
Code all the features for one segment (grouped together)
then all for the next etc. etc. rather than grouping the

1c24442a07 Change to segment_feature_data[][] structure.
This data structure is  now [Segment ID][Features]
rather than [Features][Segment_ID]

I propose as a separate modification to make the experimental
bit stream reflect this such that all the features for a segment
are coded together.

b870947d42 Removed bmi copy to/from BLOCKD
for SPLITMV and B_PRED modes.  Modified code to use the bmi
found in mode_info_context instead of BLOCKD.  On the decode
side, the uvmvs are calculated only when required, instead of
every macroblock.  This is WIP. (bmi should eventually be
removed from BLOCKD)
Small performance gains noticed for RT encodes and decodes.(VGA)

85358d04cd Fix data accesses for simple loopfilters
The data that the simple horizontal loopfilter reads is aligned, treat
it accordingly.

For the vertical, we only use the bottom 4 bytes, so don't read in 16
(and incur the penalty for unaligned access).

This shows a small improvement on older processors which have a
significant penalty for unaligned reads.

postproc_mmx.c is unused

c5f890af2c Use local labels for jumps/loops in x86 assembly.
Prepend . to local labels in assembly code.  This
allows non unique labels within a file.  Also
makes profiling information more informative
by keeping the function name with the loop name.

Alpha Lam
4e8d35a461 Copy less when active map is in use
When active map is specified and the current frame is not a key frame,
golden frame nor a altref frame then copy only those active regions.

This significantly reduces encoding time by as much as 19% on the test
system where realtime encoding is used. This is particularly useful
when the frame size is large (e.g. 2560x1600) and there's only a few
action macroblocks.

744f482350 Small boost to every other frame.
Instead of a single mid GF boost apply a few extra bits to
every other frame. This gives a very small average metrics
improvement on both derf and YT sets.

Also use min GF interval as min KF interval.
