Also a little bit of code cleanup: replacing pbi->common with cm,
pbi->mb with xd.

This flag was added to VP8 to allow a mode where MB-level skipping
was not allowed, saving a bit per mb. It was never used in practice,
and hasn't been tested in VP9, so remove it.

This is work-in-progress, it implements multiple ARF
encoding behind an experimental flag.

It adds the ability to insert multiple ARF frames into a
single ARF group. This patch implements the reordering
of the coded frames, and implements a fixed-length coding
pattern. It applies a fixed quantizer strategy based on
where the frame is in the coding sequence.

Further work to modify the rate control strategy is
ongoing and will be submitted via a set of future patches.

In this first step, each ARF group is recursively
bisected and an ARF frame added at that position in the
sequence. The recursion continues until ARF frames are
within MIN_GF_INTERVAL frames.

The code sits behind the "multiple-arf" experimental
flag ("CONFIG_MULTIPLE_ARF"). The experimental flag
"oneshotq" ("CONFIG_ONESHOTQ") also needs to be enabled
for this patch to work correctly.

This patch will use the dest buffer instead of the
predictor buffer.  This will allow us in future commits
to remove the extra mem copy that occurs in the dequant
functions when eob == 0.  We should also be able to remove
extra params that are passed into the dequant functions.

macros for rectangular block sizes under the sbsegment experiment; this
experiment is not yet functional and should not yet be used.

Clamp only the motion vectors inferred from neighboring reference
macroblocks. The motion vectors obtained through motion search in
NEWMV mode are constrained during the search process, which allows
a relatively larger referencing region than the inferred mvs.
Hence further clamping the best mv provided by the motion search may
affect the efficacy of NEWMV mode.

Synchronized the decoding process. The decoded mvs in NEWMV modes
should be guaranteed to fit in the effective range. Put a mv range
clamping function there for security purpose.

This improves the coding performance of high motion sequences, e.g.,
derf set:
foreman 0.233%
husky   0.175%
icd     0.135%
mother_daughter 0.337%
pamphlet        0.561%
