Root cause is the different default register length between x86
and x64 platform. Change spatial_layer_id to long long.

This commit added a speed feature to make the logic of calculating
skip_recode on a block level more explicit. This also enable the
feature to be enabled at speed 5 where the previous logic is too
conservative, help gain back the lost speed for --rt(-5).

This commit enables a recursive partition type search for non-RD
mode decisions. It allows the encoder to choose variable block
sizes in a 64x64 block based on rate-distortion modeling.
It improves speed -6 coding efficiency for rtc set by 2.4%. Most
of the gains come from 32-40dB range, where many sequences gain
about 5% to 20%. Local tests suggest there is no speed change.

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.
