e55f60240a Implement variance-based adaptive quantization
This should be similar to what x264 does with --aq-mode 1.
It works well with clips like parkjoy and touhou
(http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv).
At low bitrates, the segmentation signaling overhead may negate the
benefits of this feature.

(PGW) Default changed to feature OFF to allow provisional merge.

d6a59fb12c Updated encoder to handle intra-only frames
Updated the encoder to handle frames that are coded
intra-only. Intra-only frames must be non-showable,
that is, the "show frame" flag must be set to 0 in
the frame header.

Tested by forcing the ARF frames to be coded intra-
only.

Note: The rate control code will need to be modified
to account for intra-only frames better than they
are currently handled.

8e3ce1a9e3 Re-design all-zero-coeff block index buffer use
Use the zcoeff_blk buffer of PICK_MODE_CONTEXT to store the indexes
of all-zero-coeff block of the current best mode. Remove the temporary
buffer best_zcoeff_blk defined in the rate-distortion optimization
loop. This improves the speed performance by about 0.5% in all speed
settings.

f60a3910c4 Move token_cache from cost_coeffs to MACROBLOCK
This commit moves token_cache buffer into macroblock struct, instead
of defining as a local variable in cost_coeffs. This avoids repeatedly
re-allocating memory space in the rate-distortion optimization loop.

The runtime at speed 0 reduces:
bus 2000kbps, 161692ms to 159951ms
football 600kbps, 229505ms to 225821ms

  vp9_cond_prob_diff_update (encoder)
  vp9_diff_update_prob (decoder)

d9655e42b8 Change in rddiv parameter to make it a power of 2
Converts the constant rddiv parameter to 128 (from 100) and
implements RDCOST with bit-shift rather than multiplication.
Other parameters are also adjusted to roughly keep the same
balance between Rate and Distortion.

There is a slight speed-up of about 0.5-1% (at speed 0) as
testted on football_cif.

There is a slight change in performance due to small change
in the parameters.

8b175679be Masking intra mode choice adaptively
The commit changes to mask available intra prediction modes for test
based on prediction block size.

HD clips with a compression drop of 0.2%

704028d435 Experimental rate control change.
When the codec in VBR (or cq) mode hits its max q limits and is
struggling to hit a target bandwidth, the bit target per frame collapses.

In the first instance normal frames cap out at the maximum allowed
Q and then the ARF and GFs do the same. This latter behavior is not
generally desirable as GFs and ARFs are only effective from a quality
and data rate perspective if they have at lease some level of -Q delta
compared to the surrounding frames.

In this patch I define a separate max Q for GFs and ARFs that is
derived from but somewhat lower than that defined for normal frames.
In effect there is a minimum Q delta that will always be available for
GFs and ARFs regardless of the target rate and MAXQ setting.

This may of course mean that the absolute lowest rate obtainable for
a given clip is somewhat higher.
