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.
Compression and speed performance wise:
speed 1
derf -0.266%
yt -0.138%
bus at 2000 kbps: 33766ms -> 30451ms (10% speed-up)
football at 600 kbps: 48173ms -> 43786ms (9% speed-up)
speed 2
derf -0.026%
yt +0.134%
bus at 2000 kbps: 18973ms -> 17698ms (6% speed-up)

array pointer to get_filter_base() function.

This commit constrains the maximal motion search range for sub8x8
blocks to be [-1023, 1023], in the unit of full pixel.

There were two problems with the format string in
the conditionally compiled print statement. It referred
to a variable that is no longer available and it used
incorrect format specifiers.

Adds a hook that derived test classes can implement to be notified
before every call to decode a frame.

reorder the tiles based on size and their presumed complexity. this
minimizes the cases where the main thread is waiting on a worker to
complete.
