Add a new function vp9_decode_mb_tokens() that handles the switch
between different per-tx-size detokenize functions. Make actual
implementations (vp9_decode_mb_tokens_NxN()) static.

It didn't handle rd_thresh == INT_MAX, which means the reference is
unavailable.

More cleanup to do after this, but this is a good chunk of removing rtcd.

Don't declare variables if they only ever have a single value and are
used only as argument to another function call; instead, just hardcode
the value in the function call directly. Split out UV and Y coefficient
loops for clarity. Use xd->block[].qcoeff instead of xd->qcoeff + magic
to remove use of magic offset variables.

Don't declare variables if they only ever have a single value and are
used only as argument to another function call; instead, just hardcode
the value in the function call directly. Also remove unneeded brackets
around a code block, and remove the magic offsets 64 and 256 for chroma
values in the coefficient memory block.

Also fix the type (TX_SIZE instead of int).

Update the fmt_deps function to use a new sed expression to convert the
object file name generated by the compiler into the path-transformed
name of the .o and .d files.
Prior to this patch, changing a header file would not trigger an
incremental build.

This removes functions that are no longer needed and cleans up some warnings.

this prevents duplicating the same line of code in each caller of
decode_coefs().

This prevents the relatively expensive token-from-coefficient lookup
function get_token(), plus a duplicate loop..

Just like for all other block modes, b_pred tokens can be read together
before starting macroblock reconstruction. This removes special cases
for b_pred in decode_macroblock() and allows to make decode_coefs_4x4()
static in detokenize.c.
While at it, remove the redundant handling and checking of plane_type
and block_index (i) in decode_coefs_4x4(). Since the function is static,
and is called only from decode_mb_tokens_4x4(), we don't need to worry
that the arguments ever go out of sync.

Experiments with a larger set of contexts and some
clean up to replace magic numbers regarding the
number of contexts.
The starting values and rate of backwards adaption
are still suspect and based on a small set of tests.
Added forwards adjustment of probabilities.
The net result of adding the new context and forward
update is small compared to the old context from the
legacy find_near function. (down a little on derf but
up by a similar amount for HD)
HOWEVER.... with the new context and forward update
the impact of disabling the reverse update (which may be
necessary in some use cases to facilitate parallel decoding)
is hugely reduced.
For the old context without forward update, the impact of
turning off reverse update (Experiment was with SB off) was
Derf - 0.9, Yt -1.89, ythd -2.75 and sthd -8.35. The impact was
mainly at low data rates.
With the new context and forward update enabled the impact
for all the test sets was no more than 0.5-1% (again most at
the low end).

added additional motion vectors at close neighborhood of a superblock
to the list of candiate motion vectors, and removed a couple that are
further away.
The change helped std-hd set about .8% (all metrics) and smaller gain
for derf set.

A patch on compound inter-intra prediction.
In compound inter-intra prediction, a new predictor for
16x16 inter coded MBs are obtained by combining a single
inter predictor with a 16x16 intra predictor, in a manner
that the weight varies with distance from the top/left
boundary. The current search strategy is to combine the best
inter mode with the best intra mode obtained independently.
Results so far:
derf +0.31%
yt +0.32%
std-hd +0.35%
hd +0.42%
It is conceivable that the results would improve somewhat
with a more thorough search strategy where all intra modes
are searched given the best mv, or even a joint search for
the best mv and the best intra mode.

Modify the decoder to return the ending position of the bool decoder and
use that as the starting position for the next frame.
The constant-space algorithm for parsing the appended frame lengths is
O(n^2), which is a potential DoS concern if n is unbounded. Revisit
the appended lengths for use as partition lengths when multipartition
support is added.
In addition, this allows decoding of raw streams outside of a container
without additional framing information, though it's insufficient to
be able to remux said stream into a container.

this commit changed the asm file compiling in MSVC to use individually
customized build command line with object filename specified for each
input file. This allows object filenames prefixed with path name, and
avoid name collision in link time
