Adds two new vp9 parameters --min-gf-interval and --max-gf-interval
to enable testing based on frequency of alt-ref frames.
Also adds a unit-test to test enforcement of min-gf-interval.
For both these parameters the default value is 0, which indicates
they are picked by the encoder, based on resolution and framerate
considerations. If they are greater than zero, the specified
parameter is honored.
(Additional note by paulwilkins)
Note that there is a slight oddity in that key frames are also GFs and
considered part of GF only group. However they are treated as not
being part of an arf group because for arf groups the previous GF is
assumed to be the terminal or overlay frame for the previous group.

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.

Correct the ARF boost calculations to partly discount
inactive or very low energy regions of the image.
Examples (formatting bars and 0 energy areas of animated clips).

This commit moves the primitive multi-threading files from vp9
folder to vpx_thread, which will be accessible by all vpx codec.

to MB_MODE_INFO_EXT. This saves 36 bytes per 8x8 area for
both the decoder and encoder. (encoder has two MODE_INFO
buffers)

Only do the check for resizing if the feature is selected
(i.e., resize_mode = RESIZE_DYNAMIC).
And modify condition for checking to be resize_count >= window,
(since framerate can change).

Reduce boost for segment#2 for low bitrates and low-res.
This change is to reduce the rate overshoot at low bitrates.
No change in behavior, except at the very low bitrates.

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.

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.

For screen content don't refresh a block at a quantizer higher than
it was last coded at. PReviosuly at realtime speeds the encoder had a
tendency to recode a block from GOLDEN with a higher Q than it was last
coded at.
