The added vector was encoded with aq mode on, with the intent to
exercise the decode code around segment feature.

Makes the thresholds for bitrate control more leniant to
prevent test failures.

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

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.
