5f25d4c175 Reduced the size of Y1Dequant and friends to [128][2]
This patch removes the local copies of the dequantize
constants and implements John's idea as described
in "Make a local copy of the dequantized data" commit.

0ccefd2c8f Fixed mb_skip_coeff bug
When mb_skip_coeff is set, the idct is not necessary.  Prior
to this patch, the code would call idcts based on leftover
eob information.  This patch will now skip the idct for
SPLIT_MV and clear out the eobs for B_PRED, forcing the idct
to be skipped.

a53d5a4c44 Moved dequant idct into common
These functions are now used by the encoder.
This is WIP with the goal of creating a common idct/add for
the encoder and decoder.  A boost of 1.8% was seen for
the HD rt test clip used.

[Tero] Added needed changes to ARM side.

Scott LaVarnway
4a91541c94 Modified the inverse walsh to output directly
to the dqcoeff or qcoeff buffer.  The encoder would
populate the dc coeffs of the y blocks as a separate
stage (recon_dcblock) and the decoder would use a special
version of the idct.  This change eliminates the extra copy
and reduces the code footprint.

[Tero] Added needed changes to armv6 and NEON assembly.

1427205215 Changing decoder input partition API to input fragments.
Adding support for several partitions within one input fragment.
This is necessary to fully support all possible packetization
combinations in the VP8 RTP profile. Several partitions can
be transmitted in the same packet, and they can only be split
by reading the partition lengths from the bitstream.

9bf3bc9a72 Correct SPLITMV clamping
Prior to this fix, the clamping state of the last subblock partition
dominated, whereas the correct behavior is to clamp if any partition
needs clamping. This bug was introduced by v0.9.6-232-g6b25501

ed9c66f584 Remove usage of predict buffer for decode
Instead of using the predict buffer, the decoder now writes
the predictor into the recon buffer.  For blocks with eob=0,
unnecessary idcts can be eliminated.  This gave a performance
boost of ~1.8% for the HD clips used.

Tero: Added needed changes to ARM side and scheduled some
      assembly code to prevent interlocks.

Patch Set 6:  Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3)
into this commit because of similarities in the idct
functions.

e529a825f7 Fix necessary for input partitions iface to match the RTP profile
These changes fixes a glitch between the RTP profile and the input
partitions interface. Since there's no way for the user to know the
actual number of partitions, the decoder have to read the
multi_token_paritition bits also when input partitions mode is
enabled.

Included are also a couple of fixes for issues with independent
partitions and uninitialized memory reads.

c0ee870b0a clamp_mvs() using the wrong motion vector information
In the "Removed bmi copy to/from BLOCKD" commit, the copy
to the bmi in BLOCKD was eliminated.  The clamp_mvs() used
the bmi in BLOCKD, which now contains incorrect values.  This
patch fixes this problem.

every macroblock.  This is WIP. (bmi should eventually be
removed from BLOCKD)

when we have multiple non-resilient partitions.
