Adds a speed feature for fast 1-loop forw updates
Incorporates a speed feature for fast forward updates of
coefficients. This feature takes 3 values:
0 - use standard 2-loop version
1 - use a 1-loop version
2 - use a 1-loop version with reduced updates
Results: derfraw300 +0.007% (on speed 0) at feature value = 1
-0.160% (on speed 0) at feature value = 2
There is substantial speed up at speeds 2 and above for low

Fix bug in convolution functions (filter selection)
(In response to Issue 604:
https://code.google.com/p/webm/issues/detail?id=604)
There were bugs in the convolution code for two cases:
1. Where the filter table was assumed to be aligned to a
256 byte boundary. The offset of the pixel in the
source buffer was computed incorrectly.
2. Where no such alignment assumption was made. An
incorrect address for the filter table base was used.
To fix both problems, I now assume that the filter table is
256-byte aligned and modify the pixel offset calculation to
match.
A later patch should remove the restriction that the filter
table is aligned to a 256-byte boundary.
There was also a bug in the ConvolveTest unit test

At high speed settings on some clips the key frame was starting

Checking scale factors on access.
It is possible to have invalid scale factors and not access them
during decoding. Error is reported if we really try to use invalid scale
factors.

Removing useless calls to setup_{pre, dst}_planes.
Comment is wrong, we don't initialize any xd pointers. We only initialize
xd->planes[i]->dst and xd->planes[i]->pre[], which are actually initialized
for every block during the decoding.

Refactor rd_pick_partition for parameter control
This commit changes the partition search order of superblocks from
{SPLIT, NONE, HORZ, VERT} to {NONE, SPLIT, HORZ, VERT} for
consistency with that of sub8x8 partition search. It enable the use
of early termination in partition search for all block sizes.
For ped_area_1080p 50 frames coded at 4000 kbps, it makes the runtime
goes down from 844305ms -> 818003ms (3% speed-up) at speed 0.
This will further move towards making the in-search partition types
configurable, hence unifying various speed-up approaches.
Some speed 1 and 2 features are turned off during the refactoring
process, including:
disable_split_var_thresh
using_small_partition_info
Stricter constraints are applied to use_square_partition_only for
right/bottom boundary blocks. Will bring back/refine these features
subsequently. At this point, it makes derf set at speed 1 about
0.45% higher in compression performance, and 9% down in run-time.

Fixes on feature disabling split based on variance
Adds a couple of minor fixes, which may be absorbed in Jingning's
patch. Thanks to Guillaume for pointing these out.
Also adjusts the thresholds for speed 1 and 2 to 16 and 32
respectively, to keep quality drops small.
Results:
--------
derfraw300: threshold = 16, psnr -0.082%, speedup 2-3%
