Condition usage of rc.frames_since_golden to non-svc mode.

rc.frames_since_golden, which is used in non-svc mode to add second reference,
was causing, under certain condiiton, the turning off of golden reference
for svc case.

1. The RD scores obtained during the tx size selection were stored in the
tx cache, and used to help make the tx decision for the following frames.
This wasn't used anymore in VP9 encoder. Recovered the related decision
making code from 1.5+ years ago, and borg tests didn't show any quality
gain. This patch removed it to lower the complexity.

2. An optimization was done after the above refactoring. If the tx_mode
is not TX_MODE_SELECT, we only need to test the chosen tx size instead
of all posible tx sizes. This gave a 1.5% average speed gain at speed 2,
and a 1% average speed gain at speed 3.

Changes to allow more use of rectangular partitions at
speeds 1 and 2 for content classed by the first pass as
animation and for blocks near the active image edge.

This has quite a big impact in quality for the animated
test sequence but also hurts encode speed for speed 2.

For other content types the impact on both speed and
quality is small.

Added some plumbing for detection of internal vertical
image edges.

Change-Id: I3fc48de2349f8cb87946caaf0b06dbb0ea261a9a

Change speed features / behavior for split mode when there
is an internal active edge (e.g. formatting bars).

Remove some threshold constraints in rd code near the active
edge of the image.

Add some plumbing for left and right active edge detection.

Patch set 5. Limit rd pass through for sub 8x8 to internal active edges.
This takes away any speed penalty for most clips but keeps the enhanced
edge coding for the more critical case of internal image edges

Change-Id: If644e4762874de4fe9cbb0a66211953fa74c13a5

If the pre-selected partition size (from variance partition) is
32x32, also apply nonrd partition search for 32x32 and 16x16 size.

Overall small positive gain in metrics, average ~1%.
Some visual improvement, for lower resolutions.

Change-Id: I69cb425bda94f7d13d34c451ab30e9276335a30e

Added code to reduce the minimum partition size searched
for super blocks at or straddling the edge of the image.

If the first pass has detected formatting bars the "active" edge
may not be the real edge.

Change-Id: If006abb2224acaf326df3c2be09e77e967662107

Keep the same transform cutoff and partition selection
for speed 5 as in speeds >=6 (non-rd speed settings).

Existing setting for key frame at speed 5 allowed transform size
up to 32x32 on key frames, and did not allow for 4x4 block partition size.
This created more visual artifacts on first few frames.

avgPSNR/overallPSNR/SSIM gains of 0.2/0.7/0.8 for rtc_derf(low-res) set,
and 0/0.7/1.1 gains for rtc set.

and added to MACROBLOCKD.

Change-Id: I0e60aaa9f84bcc9f2376d71bd934f251baee38db

For speed 5 real-time mode, the selection of the partition size for
superblocks on the segment (aq-mode=3) uses the non-rd recursive
pick partition search, and can sometimes select 64x64.

For low resolutions, visually better to limit this to 32x32.

this macro was used inconsistently and only differs in behavior from
DECLARE_ALIGNED when an alignment attribute is unavailable. this macro
is used with calls to assembly, while generic c-code doesn't rely on it,
so in a c-only build without an alignment attribute the code will
function as expected.

Impose a limit on the rd auto partition search based on
the image format. Smaller formats require that the search
includes includes a smaller minimum block size.

This change is intended to mitigate the visual impact of
ringing in some problem clips, for smaller image formats.
