Re-arrange the multiplication and right shift operations to avoid
integer overflow in choose_partitioning.

This commit removes the pred_mv_sad comparison from rtc motion
search, given that a stronger comparison has been done at the
mode search level to eliminate unlikely selected reference frames.

This commit enables the rtc coding mode to run integral projection
based motion search for golden reference frame. It improves the
speed -6 compression performance by 1.1% on average, 3.46% for
jimred_vga, 6.46% for tacomascmvvga, and 0.5% for vidyo clips. The
speed -6 is about 6% slower.

Make the vp9_int_pro_motion_estimation() function return zero
motion vector if high bit depth is turned on, instead of removing
it from compiled codes.

Set flags=0 if layering_mode=0, and set static_thresh=1.

Added clamp on the rate correction factor after
it has been scaled.

Only update the rd_thresh factors for modes sharing same reference
frame. This helps overall compression of 6 and 7 by .13% and .19%
respectively without any noticeable speed difference.

Some rate control adjustments to control overshoot
in the constrained quality mode.

For non-SVC 1 pass CBR: make the GF update interval a multiple of the
cyclic refresh period, and use encoding stats to prevent GF update at certain times.

Tx_totals counters weren't handled correctly in multi-thread
case, which caused the mismatch while encoding using threads > 1.
This patch fixed that.

The return value from vp9_compute_qdelta_by_rate, which is
a delta value for the quantizer, could never be 0 if
(qindex == rc->worst_quality).

This occurs because target_index was setup unconditionally
in the loop and yet the loop counter stopped at
(rc->worst_quality - 1).

Choose_partition uses only the last frame as reference frame in making
partition decision, this commit adds the check on how well Golden
frame with (0,0) predicts the current block, and uses GF(0,0) as
basis for partition decision if it produces better prediction.

The commit improves rtc speed 6 and 7 encoding by 0.14% and 0.19%
respectively.

When golden reference frame is refreshed, the next frame has both
its last and golden reference frames point to the same reference
frame in real-time coding mode. Experiments suggest that using
two separate reference frames for frames right after golden refresh
frame does not provide further compression performance advantage.
This commit hence retains the current encoder implementation and
shuts off the mode search over golden reference frame in this case.

It makes the encoder run slightly faster at no coding performance
change.

Force 64x64 partitioning when a whole superblock is SEGMENT_LVL_SKIP. This
drops encode times of screens mostly at rest by 20%.

Adjustment previously only enabled in VBR mode.

This patch allows adjustment of min and max q for CBR
and adjustment of max q only for CQ mode.
