22694ca1ad Change txfm_type decision
The changing in intra coding to base on transform block, i.e. pred->
txfm->quant->dequant-itxfm->recon, made all blocks within a prediction
unit behave consistently, there is no longer a need to handle blocks
differently based on the position within a predicitn block. So this
commit simplifies the decision of transform type to be based on
prediction mode only.

ae10319520 Make comp_inter_inter support 4x4 partition coding
This commit refactors the iterative motion search for compound
inter-inter mode, to make it support all partition types including
4x4/4x8/8x4 block sizes.

7ac5ac52f9 Merge 4x4 block level partition into codebase
Move 4x4/4x8/8x4 partition coding out of experimental list.

This commit fixed the unit test failure issues. It also resolved
the merge conflicts between 4x4 block level partition and iterative
motion search for comp_inter_inter.

de4d682ca4 Using 128 entry look up table for coef models
Reverts to using 128 bit LUT for the coef models rather than 48
to ease hardware implementation.

Also incorporates some cleanups including removing various
hooks to support different lookup tables based on block_type and
ref_type.

8ba92a0bed changes intra coding to be based on txfm block
This commit changed the encoding and decoding of intra blocks to be
based on transform block. In each prediction block, the intra coding
iterates thorough each transform block based on raster scan order.

This commit also fixed a bug in D135 prediction code.

TODO next:
The RD mode/txfm_size selection should take this into account when
computing RD values.

f153a5d063 Make the intra rd search support 8x4/4x8
This commit allows the rate-distortion optimization of intra coding
capable of supporting 8x4 and 4x8 partition settings.

It enables the entropy coding of intra modes in key frame using a
unified contextual probability model conditioned on its above/left
prediction modes.

Coding performance:
derf 0.464%

ad484fc6be Add support for armv7-win32-vs11
The arm assembly files are named .s after conversion, to reuse
as much of the existing makefile infrastructure for conversion to
gas format as possible. Within the generated visual studio project,
only the converted assembly sources are available, which might not
be optimal for actually developing it, but is acceptable for
just building the library.

Multithreading is disabled since the traditional win32 threading
functions aren't available on WinRT/Windows Phone 8.

Building of vpx itself and the examples succeed, while building the
tests fail due to them using functions not available in the
windows store/windows phone API subsets - therefore the unit tests
are disabled.

This works for building in Visual Studio Express 2012 for Windows
Phone, while Visual Studio Express 2012 for Windows 8 (for
"Windows Store" apps) seems to reject the vcxproj files due to
not supporting "classic style native application or managed
projects". The built static library should be compatible with that
platform though.

df037b615f Adding API to read/write uncompressed frame header bits.
The API is not final yet and can be changed. Actual layout of

clr_type, error_resilient_mode, refresh_frame_context,
frame_parallel_decoding_mode from first compressed partition to
uncompressed frame part.

07443f1589 Refinements on modelcoef expt to reduce storage
Uses more aggrerssive interpolation to reduce storage for the
model tables by almost more than half. Only 48 lists of probs are
stored (as opposed to 128 before), corresponding to ONE_NODE
probabilities of:
1,
3, 7, 11, ..., 115, 119,
127, 135, ..., 247, 255.

Besides, only 1 table is used as opposed to 2 before. So the overall
memory needed for the tables is just 48 * 8 = 384 bytes.

The table currently used is based on a new Pareto distribution with
heavier tail than a generalized Gaussian - which improves results on
derf by about 0.1% over a single table Generaized Gaussian.

Results overall on derfraw300 is -0.14%.
