Fixes rate control partially in one-pass non-cbr case to achieve a
bitrate close to the one desired. Previous version was way off at
the high bitrate end.
Also includes several one-pass rate control cleanups and refactoring.
On derfraw300, one-pass encoding is now 19% off from two-pass speed
0 encoding, down from 35%.

Moved a few features with low impact on compression form -5 to -4 and
increased adaptive_rd_thresh for -5.

This avoids calls to get_unsigned_bits() with constants and
replaces hard to trace loops with simpler structures.

This patch adds a buffer-based rate control for temporal layers,
under CBR mode.
Added vpx_temporal_scalable_patters.c encoder for testing temporal
layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).
Updated datarate unittest with tests for temporal layer rate-targeting.

As pointed out by Dmitry and James, "partial" is a Microsoft-
specific c++ keyword, and it is renamed.

This commit added a logic to prevent the inter_filter type from being
changed if the default interp_filter mode is not switchable. Also, it
sets the default interp_filter to BILINEAR at very and super fast rtc
encoding modes

--rt --cpu-used=-5 uses the progressive rtc mode
--rt --cpu-used=-6 uses the new super fast rtc mode

* Avoid unnecessary type erasure
* Prune unused/duplicate fields from struct rdcost_block_args
* Make struct rdcost_block_args a local

When showing a previously decoded frame, i.e. when
show_existing_frame=1, the update of the
last_show_frame flag must be disabled.
This is to ensure that the last_show_frame flag
reflects the state of the flag for the immediately
previously decoded frame rather then the value that
was forced to ensure that a previously decoded frame
would be displayed.
This patch also adds a test vector to verify that the
display_existing_frame flag works as expected. Code
for generating the test vector can be found in this
patch:
