prevent test failures.

Add an option for libvpx to return the least recently used
frame buffer.

Change-Id: I886a96ffb94984f1c42de53086e0131922df3260

VP9 decoder can now use frame buffers passed in by the application.

Increased threshold(t) for interp filter search. This sped up the
encoder with some PSNR loss.

Borg tests were ran at speed 2.
t = 100, PSNR loss:
-0.710%(derf); -0.561%(stdhd); -0.647%(youtube)
speedup:
9%(derf); 3%(stdhd); 5.7%(youtube)

t = 500, PSNR loss:
-1.687%(derf); -1.665%(stdhd); -1.664%(youtube)
speedup:
18%(derf); 10%(stdhd); 8%(youtube)

Corrected a typo that set rc_2pass_vbr_minsection_pct to
two different values on consecutive lines. Second line
should have set rc_2pass_vbr_maxsection_pct.

This commit enables an adaptive prediction filter type selection
for sub8x8 block sizes. In speed 1, it re-uses the filter type of
collocated 8x8 block if it is tested in the rate-distortion optimization
loop, for the sub8x8 blocks. Otherwise, it runs the normal test
over all the three filter types. In speed 2, it re-uses the 8x8
block's prediction filter type, if available. Otherwise, force it
to be EIGHTTAP.
