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.

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.

Merge code blocks for different transform sizes; use MACROBLOCKD as a
temp variable where that leads to smaller overall source code; remove
duplicate code under #if CONFIG_HYBRIDTRANSFORM/#else blocks. Some style
changes to make it follow the style guide a little better.

Also make some minor stylistic changes to bring the code closer to
the style guide. Remove distinction between inter and intra transform
functions, since both do exactly the same thing except for the check
against SPLITMV for the second-order transform. Remove some commented
out debug code. Remove 8x8/16x16 transform code in encode_inter16x16y(),
since the first-pass only uses 4x4 anyway.

Also make some minor stylistic changes to bring the code closer to
the style guide. Remove checks against i8x8/bpred in the mb-codepath,
since these do individual block reconstruction and thus don't go through
this codepath.

Entropy coding takes care of this anyway, and this causes changes to
the txfm size assigned to skip blocks, which can affect the loopfilter
output, thus causing encoder/decoding mismatches.

The update_mb_segmentation_map flag was being signalled earlier than
other data dependent on that flag. Consolidate this data so it's
parsed within the same if-scope as the flag is originally parsed in.

A variety of issues related to tangling of various hybrid transform
experiments.
Change-Id: I84dac65ff513f8b024407760df55fffa95e198de

This commit fixes unsafe simd / floating point interactions arising
from the current hybrid and 16x16 transform implementation.
These led to a raft of bugs and issues when the project was
built using VS2008 for Win32 though they did not show up with
the unix builds.
Gerrit makes a meal out of presenting the fix but all I have actually
done is indent the body of each function that uses floating point by
one level and bracket with emms instructions using the function
vp8_clear_system_state(). See below.
function () {
vp8_clear_system_state();
{
... function body
}
vp8_clear_system_state();
}
This is almost certainly over the top in terms of number of emms
instructions but is a temporary measure pending implementation of
integer variants of each function to replace the floating point.
Limited testing suggests that this fixes the problems that arose for
Win32 VS2008 when the hybrid or 16x16 transforms were enabled.

Separates the entropy coding context models for 4x4, 8x8 and 16x16
ADST variants.
There is a small improvement for HD (hd/std-hd) by about 0.1-0.2%.
Results on derf/yt are about the same, probably because there is not
enough statistics.
Results may improve somewhat once the initial probability tables are
updated for the hybrid transforms which is coming soon.

With this change, even if hybridtransform8x8 experiment is off,
8x8 dct is used for the I8x8 mode. However note that the gains
observed with the hybridtransform8x8 experiment will now be less,
since part of the gain is now merged in.

The high-precision (1/8) pel bit is turned off if the reference
MV is larger than a threshold. The motivation for this patch is
the intuition that if motion is likely large (as indicated by
the reference), there is likley to be more motion blur, and as
a result 1/8 pel precision would be wasteful both in rd sense
as well as computationally.
The feature is incorporated as part of the newmventropy experiment.
There is a modest RD improvement with the patch. Overall the
results with the newmventropy experiment with the threshold being
16 integer pels are:
derf: +0.279%
std-hd: +0.617%
hd: +1.299%
yt: +0.822%
With threshold 8 integer pels are:
derf: +0.295%
std-hd: +0.623%
hd: +1.365%
yt: +0.847%
