It currently counts the probability that the branch is true, but it
should count the probability that the branch is false.

Allows B_VL_PRED & B_LD_PRED modes to be used for all blocks
within a MB in B_PRED mode. These modes were temporarily
disabled with super-block coding.

First sse2 version of vp8_mbloop_filter_vertical_edge(). For now,
intrinsics are being used until the bitstream is finalized. This function
will be revisited later for further performance improvements.
For the test clip used, a 34+% decoder performance improvement
was seen. This will vary depending on material.

There were several different methods for calculating bitstream
probabilities in use. Consolodate these into a pair of functions,
get_prob() and get_binary_prob().

When run with no arguments, report warnings in the diff between the

Pass the bool coder to be used explicitly. This avoids cases where two
different bool coders can be addressed from the same function. Also be
more consistent with bool coder variable naming, start to standardize
on 'bc'.

Separates the logic on transform type selection previously spread out
over a number of files into a separate function. Currently the tx_type
field in b_mode_info is not used, but still left in there to eventually
use for signaling the transform type in the bitstream.
Also, now for tx_type = DCT_DCT, the regular integer DCT is used, as
opposed to the floating point DCT used in conjuction with hybrid
transform.
Results change somewhat due to the transform change, but are within
reasonable limits. The hd/std-hd sets are slightly up, while derf/yt
are slightly down.

First sse2 version of vp8_mbloop_filter_horizontal_edge(). For now,
intrinsics are being used until the bitstream is finalized. This function
will be revisited later for further performance improvements.
For the test clip used, a 31+% decoder performance improvement
was seen. This will vary depending on material.

Prior to this patch, if there were any lint errors, this script would
exit with an error, even if those errors were not in the hunks being
tested by this script. This change makes it so that if any lint lines
are printed, an error is returned.

This commit moves a bit of data that ended up packed with the
modes/mv/residual partition during the change to interleaved encoding
into partition 0 where it belongs.

Packs the bitstream with each mb's residual following its mode/mv
information.
TODO: There are still a few fields that should be packed into partition
0 but are included in partition 1, due to them being serialized from
write_kfmodes/pack_inter_mode_mvs, which execute after the first
partition is finalized. These need to be separated out into a separate
function, similar to mb_mode_mv_init() in decodemv.c.

Rather than decoding all modes/mvs separately, decode them per MB. This
forces the mode which was already used form the CONFIG_NEWBESTREFMV and
CONFIG_SUPERBLOCKS experiments, and is a precursor to changing to
interleaved encoding.

It is essentially a duplicate of mode for RD-only purposes. Removing it
saves us 4 bytes per B_MODE_INFO, or ~0.5MB for a 1080p video encode.

The variable is essentially a duplicate of mode for RD-only purposes.
Removing it gives identical results, and saves 4 bytes per macroblock
(i.e. 32.5kB for a 1080p HD video encode).

This way a caller doesn't need to implement the logic for which (and how
many) tokens to write out to stuff one macroblock worth of EOBs. Make
the actual function implementations static, since they are now only used
in tokenize.c; also do some minor stylistic changes so it follows the
style guide a little more closely; use PLANE_TYPE where appropriate,
remove old (stale) frame_type function arguments; hardcode plane type
where only a single one is possible (2nd order DC or U/V EOB stuffing);
support stuffing 8x8/4x4 transform EOBs with no 2nd order DC.

Change the macros PLANE_TYPE_{Y_NO_DC,Y2,UV,Y_WITH_DC} to a typed enum,
and use this typed enum consistently across all places where relevant.
In places where the type is implied (e.g. in functions that only handle
second order planes or chroma planes), remove it as a function argument
and instead hardcode the proper enum in the code directly.

Also merge the three occurrences of 4x4 chroma block writing into a
single function, and call that function instead of duplicating the
4x4 chroma tokenization code in 3 places.
