Brings back most of Jim's previous patch for choosing
partitioning based on variance while making it compatible
with the current state of the code. Also adds a
nonrd_use_partition() function to recursively encode for any
arbitrary sb_type decisions within a 64x64 block; and
includes some refactoring.
Currently, when the VAR_BASED_PARTITIONING mode is turned on
for speed 7, there is a 10+% speed-up observed.
Experiments/improvements with this new partitioning method
will be conducted subsequently.

Clean-ups include
a. redundant code in rt -5 speed feature settings
b. code that guarantees square block availability in
rd_auto_partition_range()

The block size used for non-RD mode decision in FIXED_PARTITION
setting was uninitialized. This commit fixes it by setting block
size to be BLOCK_16X16.

Adds a fast diamond search which is about 5% faster than FAST_HEX
with only a 0.1% drop in psnr when turned on for both speeds 5 and 7.
This search is turned on for speed 7.

Set speed features before running frame encoding. This avoids
redundant RD threshold calculation in key frame coding.

* Remove all non-DC intra modes for BLOCK_32x32 and up
* Remove all intra modes for blocks bigger than BLOCK_32x32
* Remove ZEROMV for BLOCK_32x32 and up
* Only consider NEARESTMV for blocks bigger than BLOCK_32x32

This patch adds a new speed feature which doesn't do the rather
expensive entropy context lookup or save to the table, while
doing costing.
The speed up on desktop36p.y4m is around 10% other clips much less.
On the RTC test set this was + 1% in overall datarate.

The function has evolved over time, now only calls vp9_rtcd(), so this
commit removes the function and changes to call vp9_rtcd() directly.
Change-Id: I8cfa6190daa4b28f6f3d1e11bb3a07f9c95322bf
Adds a speed 8 to VP9 where only the nearestmv (0 mv) is searched.
This seems to be about the same speed as vp8 speed 5.
Adds a new speed feature to disable inter modes based on a mask for
each blocksize.
Adds code for having lower complexity motion search methods
in nonrd pick mode function, even though speed 7 still uses DIAMOND
search for now.
Also uses HEX search for speed 6 rather than FAST_HEX which improves
psnr by 0.56% without any noticeable speed drop (tested on gipsmotion).

There was a bug in the previous code that if GOLDEN was better than
LAST neither would be used. LAST would get turned off due to superior
GOLDEN quality then all GOLDEN modes would get skipped.

Removing all copies of identical vp8_mse2psnr/vp9_mse2psnr functions.
Using vpx_sse_to_psnr() instead in all places.

The commit change to use partitions sizes directly from last frame
for frames directly where last frame selects partitions sizes based
on coding efficiency.
On --rt --cpu-used=-5, the change hurts compression by 4% but reduces
encoding time by ~20%
Change-Id: Ia68665e5c8489b7bfcf5fac7768332fba88928e6
Adds a method for determining a fixed size partition based on
variance of a 64x64 SB. This method is added to rtc speed 6.
Also fixes a bug in rtc_use_partition() and includes some
refactoring related to partitioning search, and some cosmetics.
Currently compared to speed 5, the coding efficiency of speed 6
is -19% and that of speed 7 is -55%, in cbr mode.

If sf->disable_split_mask is DISABLE_ALL_SPLIT, disable
sf->adaptive_pred_interp_filter to avoid unnecessary operations.
Change-Id: Icb59174b2f4e9a3c3c16a696deb8018e5bd999eb
Moves the existing speed 6 to speed 7 and adds an
intermediate level 6 which is roughly in between
speeds 6 and 7 in both speed and coding efficiency.
Also includes some minor fixes/adjustments.

When non-RD coding decision is used in rtc mode, the alt reference
is not used for inter frame prediction. This commit disabled alt ref
option whenever speed -6 is used.
