By default, the activity masking is used with PVQ.
In addition to '--enable-pvq', '--enable-daala-dist' is also
required by configure to use the activity masking.

Change-Id: I5100a1db992f0e693e61daf5439de8ae8c64a752

For fixed-point version of PVQ, which is current default,
added MAXI(1, ) to limit the minimum companded or expanded gain to be one.
Previously, gain compand/expand function, which is invoked when
activity masking is enabled, sometimes outputs zero
then triggered the assert(gain != 0).

Metric change from floating-pt to fixed-pt PVQ is:

Fixes make clean && make runs (single and multi job) via addition of
new target aom_rtcd that all lib targets depend on. Target includes
the RTCD definition perl files, the output H files, the C files and
rtcd.pl itself.

Also,
- Adds list of lib targets (used to propagate the aom_rtcd dep)
- Use the correct symbol for av1 RTCD gen (aom_av1_rtcd -> av1_rtcd)

Piecewise linear fit without activity masking on subset3 intra
and objective-1-fast inter, by simple linear regression.

In combination with 79c0f32c "Remove DCT from od_compute_dist_8x8",
this gives a even trade between perceptual and non-perceptual metrics.

These are optimized for EOB_TOKEN being associated
with the current position, not the previous.

CBP tables cover EOB_TOKEN for the the whole block.

This change causes a performance regression until
EOB_TOKEN is merged into the coding scheme.

This experiment implements the idea of the uniform tri-prediction,
which adds a 3rd inter prediction on top of the existing compound
inter bi-prediction. The final predictor for an inter-coded block is
the average of the compound bi-predictor and the third predictor,
which is indentified by a third reference frame and a third motion
vector.

This fixes the following mismatch bugs:
* At the bitstream level, the decoder would not read the delta_qindex
  information for supertx blocks, but the encoder always sent it,
  leading to the encoder and decoder becoming misaligned.
  The delta_qindex information is still required for supertx blocks,
  so change the decoder to read it.
* In addition, the quantizer was not properly adjusted for supertx
  blocks at the decoder. We copy the quantizer setup code from
  non-supertx blocks.

Since this does not change the encoder, it should not have any
quality impact.
