Adds some high-level hooks for profile 2 before further
progress on the implementation.

According to the definitiion in this patch:
1. Profile 2 only supports 10 or 12 bit color but not 8
2. Profile 2 supports all color sampling modes: 444, 422 and 420,
and alpha plane.
3. Profile 3 is currently undefined.

Please consider the definition carefully and suggest modifications
to the definition as needed.

Turns off the DISABLE_RC_LONG_TERM_MEM macro and makes other changes
in the way the bits are updated, to make 2-pass rate control track
target bitrates closer.

While encoding a frame, its last frame source can be used to give
acurate motion information. This patch prevents last frame to be
overwritten so that it is available during current frame encoding.

The last source is scaled when it is necessary. cpi->Last_Source
points to the last source frame.

This commit optimizes the bit allocation for the non-RD coding flow.
It applies slightly better quantizer to the frames, where all blocks
run a non-RD partition search. Such frames typically have better
rate-distortion trade off, thus improving the reconstruction quality
for next few frames reference at reasonably low increment in rate
cost.

The coding performance for rtc set at speed -5 with error-resilient
tuned on and rate control set as cbr is improved by 19.58%. It improved
the coding speed by about 10% for a portion of local test clips.

This commit adjusted the speed steps in rt mode to make the steps
more evenly spaced on speed and quality, specifically:
1. Merged 3 and 4 into one single step 3 and removed confilicting
features.
2. Move 8, 7, 6, 5 to be 7, 6, 5, 4 repsectively.

Small speed gain for speed 1.

Quality is generally a little up for speed 2.

Speed 3 was similar to speed 4 but now positioned more
evenly between 2 and 4 speed and quality wise.
   (opsnr +5.6% ssim +8.25% across all sets)

Speed 4 is a little slower than before but sizable quality gains.
   (opsnr +3.7% ssim +6.8% across all sets)

The code has been cleaned up a bit so that for each incremental
speed step changes over the previous speed step are applied.
This makes it easier to see what is changing from one setting to
the next.

Allow tx search for ARF and GF helps quality but a little slower.
Setting subpel_iters_per_step to 1 improves encode speed.
Setting sf->mode_skip_start = 10 improves speed.

Initial local results suggest overall impact on quality is neutral
but encode is up to 15% faster.

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.
