This commit simplifies the reference motion vector part for sub8x8
block coding in RTC mode and reduces the required local variables.

This commit enables sub8x8 inter block coding for RTC mode. The
use of sub8x8 blocks can be turned on by allowing
choose_partitioning function to select 4x4/4x8/8x4 block sizes.

Properly set the corresponding scaling factor of the reference
frame in the non-RD mode decision process. This allows the mode
search process to account for the scaled reference frame when
selecting coding mode.

Local variables used at the setjmp() site need to be marked volatile.
Relevant excerpt from the 'man longjmp':
===============
The values of automatic variables are unspecified after a call to
longjmp() if they meet all the following criteria:
· they are local to the function that made the corresponding setjmp(3) call;
· their values are changed between the calls to setjmp(3) and longjmp(); and
· they are not declared as volatile.

This commit adds a guard condition to the intra mode test skip
control in RTC coding mode. If all inter modes are skipped, force
the encoder to check intra mode. It avoids situations where the
encoder processes without properly assigning required mode
information.

Initial patch to remove get_zbin_mode_boost() and
cpi->zbin_mode_boost.
For now sets a dummy value of 0 for zbin extra pending
a further clean up patch.

The alternate reference frame is disabled in non-RD mode. No need
to keep the related entries in the THR_MODES array.

In RTC coding mode, the alternate reference frame modes and compound
inter prediction modes are disabled. This commit reworks the
related mode search threshold update process to skip interacting
with these coding modes. It provides about 1.5% speed-up for speed
-6 on average.

This commit removes undefined value options of cpu-used for VP9 and
changed vpxenc prompt to reflect the usable range of [-8,8]

Use a temporary variable to store the transform size associated
with the best intra mode and restore the mode_info if the overall
best mode is intra mode.

This commit explicitly set the second reference frame type to be
NONE in key frame coding mode. This fixes a subtle dependency of
reference motion vector used by next inter frame on mode_info
reset before key frame coding.

Where there is very subtle motion, especially when combined
with low spatial complexity, the codec sometimes fails to quickly
pick up the ambient motion field.
Once it has been established though the field propagates well using
Nearest and Near MV.
This patch looks specifically at the case where the Nearest and Near
have not been established as non zero vectors and in this case
discounts the cost of searching for a new vector in the rd code.
This will almost certainly have some implications in terms of encode
speed but it should be possible to mitigate the impact in a subsequent
using first pass stats and the local spatial complexity.
Average results for test sets approximately neutral.

Change 72141 introduced a new use of vp9_avg_4x4.
This call needs to switch to using vp9_highbd_avg_4x4
when performing high bitdepth encodes.

When multiple intra modes are tested, the previous mode info
update process may overwrite the selected best intra mode and make
the final selection use an inter mode. This commit fixes this
issue by moving the mode_info reset outside the intra mode search
loop.

If vp9_pick_inter_mode works properly, it should at least check
one coding mode and hence get best_tx_size assigned a valid value.
There is no need to initialize best_tx_size with a legitimate
value before starting the mode search.
