Preparation for project restructuring.
Added vp9_ prefix on some function names that have global scope.
Added static declaration on some that dont.

Cleaned up some inconsistent references using both xd-> and
x->e_mbd. to access the same data structure in the same function.

Coding and costing of mv reference signal.

Issues in updating MV ref with COMPANDED_MVREF_THRESH
to be resolved. Ideally the MV precision should be defined based
on absolute MV magnitude not as now the MV ref magnitude.

Update to mv counts moved into bitstream.c because otherwise
if the motion reference is changed at the last minute the encoder
and decoder get out of step in terms of the counts used to update
entropy probs.

Code working on a few test clips but no results yet re benefit vs
signaling cost and no tuning of red loop to test lower cost alternatives
based on the available reference values.

Patch 3. Added check to make sure we don't pick a reference
that would give rise to an uncodeable / out of range residual.

Patch 6-7: Attempt to rebase. OK to submit but best to leave flag off for now.

Patch 9. Remove print no longer needed.

There is a macro DEFAULT_INTERP_FILTER defined in encoder/onyx_if.c that
is set as EIGHTTAP for now - so SWITCHABLE is not really used. Ideally,
this should be SWITCHABLE but that would make the encoder quite a bit slower.
We will change the default filter to SWITCHABLE once we find a faster way to
search for switchable filters.

For splitmv, where partitioning is 8x16, 16x8 or 8x8, this patch
uses the 8x8 transform (instead of the 4x4) if txfm_mode is
ALLOW_8X8 or ALLOW_16X16. For TX_MODE_SELECT, splitmv can indicate
which of the 2 transform sizes (4x4 or 8x8) it wants to use.

Gains (with hybridtx4x4/8x8/16x16 and tx_select experiments
enabled) on derf: +0.9%, HD: +0.4%, STD/HD: +0.8% (SSIM or overall
PSNR, both metrics show similar improvements).

This can be used to distinguish between 16x8, 8x16, 8x8 and 4x4
partitioning modes when choosing splitmv as a MB mode.

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.

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.

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).

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.

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.
