Marco Paniconi
36f61aa836 Set min_block_size for aq_mode=3 to 8x8.
For real-time mode under cbr, this increases the gain (5-10%)
for speed 5 (none/little change for 6), on vc-clips.

97f4fb7b5f Rate ctrl changes to track target bitrates closer
Turns off the DISABLE_RC_LONG_TERM_MEM macro and makes other changes
in the way the bits are updated, to make 2-pass rate control track
target bitrates closer.

751d002f2f Adjust rate allocation in non-RD coding mode
This commit reduces the frequency of frames using finer quantizer
in non-RD coding flow, and slightly tune up the quantizer resolution
when used. It provides 1.7% compression gains in speed -5 at no speed
difference.

769cd78ff2 Add speed feature for recode tolerance.
The new tolerance is a little higher than before (especially
for kf/gf/arf) so this change gives an encode speed up
for some clips up for speeds 0-2.

939f0e7444 Remove the q division by 3 for first frame.
This code/setting was actually not used (since speed features were not set on first frame,
until a recent change) and should be removed.

In CBR mode, the q value for the first frame can be controlled by setting
the target size via the parameters rc_buf_initial_sz (and max_intra_size_pct).

4a9928e5eb Make last frame source available in current frame encoding
While encoding a frame, its last frame source can be used to give
acurate motion information. This patch prevents last frame to be
overwritten so that it is available during current frame encoding.

The last source is scaled when it is necessary. cpi->Last_Source
points to the last source frame.

99893f2410 Apply finer quantizer to partition search frames in non-RD flow
This commit optimizes the bit allocation for the non-RD coding flow.
It applies slightly better quantizer to the frames, where all blocks
run a non-RD partition search. Such frames typically have better
rate-distortion trade off, thus improving the reconstruction quality
for next few frames reference at reasonably low increment in rate
cost.

The coding performance for rtc set at speed -5 with error-resilient
tuned on and rate control set as cbr is improved by 19.58%. It improved
the coding speed by about 10% for a portion of local test clips.

4f857bacd2 [BITSTREAM]Fix the scaling calculation
For very large size video image, the scaling calculation may need use
value beyond the range of int. This commit upgrade the value to 64bit
to make sure the calculation do not wrap around INT_MAX.

The change corrected the decoder behavior.

The bug affects only very large resolution video because the scaling
calculation was sufficient for image size smaller than 2^13.

This resolves issue:

6fc20a8434 Adjust rt speed steps.
This commit adjusted the speed steps in rt mode to make the steps
more evenly spaced on speed and quality, specifically:
1. Merged 3 and 4 into one single step 3 and removed confilicting
features.
2. Move 8, 7, 6, 5 to be 7, 6, 5, 4 repsectively.
