This commit changed how q is validated in lossless mode. With this
commit, when --lossless=1 is specificed at commandline, --min-q and
--max-q are now ignored. This is to make the option non-ambiguious.

This is an initial attempt to allow variable block size partition
in non-RD coding flow. It tests 8x8, 16x16 and 32x32 block size per
64x64 block, all using non-RD mode decision and the associated rate
distortion costs from modeling, then selects the best block size to
encode the entire 64x64 block. Such operations are triggered every
other 3 frames. The blocks of intermediate frames will reuse the
collocated block's partition type.
It improves the compression performance by 13.2%. Note that the gains
are not evenly distributed. For many hard clips, the compression
performance is improved by 20% to 28%. Local speed test shows that
it will also increase runtime by 50%, as compared to speed -7. It is
now enabled in speed -6 setting.

1. Save stats for each spatial layer
2. Add frame buffer management for svc first pass rc
3. Set default spatial layer to 1
4. Flush encoder at the end of stream in test app
This only supports spatial svc.

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.

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).
