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)

For VP9, lossless coding is enabled by passing 0 for both min_q and
max_q. This is a valid configuration, and should not be warned.

In lossless coding, distortion is always 0. Early exit based on this
metric was incorrect.
This CL also changed to use best_rd instead of distortion as the metric
for easly exit as requested by Jim.

Removed an adaptive rate correction factor that was having
a negative impact on quality in many clips. This factor
was influencing the Q range available to each frame
independently of the bits allocated to each.

Writing custom coeff branch count calculation (which is much clearer) in
adapt_coef_probs() function. Removing vp9_treecoder.c file.

Includes various cleanups.
Streamlines the interfaces so that all rate control state
updates happen in the vp9_rc_postencode_update() function.
This will hopefully make it easier to support multiple
rate control schemes.
Removes some unnecessary code, which in rare cases can casue
a difference in the constrained quality mode output, but
other than that there is no bitstream change yet.

Removed calls to vp9_update_mode_info_border since
they immediately followed code that initialized the
entire buffer to 0.

Buffer 0 would never be decremented, so it could only be used
once.

The old code would start in a mixed state, where all the reference
frames were pointing to frame buffer 0, but the reference counts
were 0. This is why we needed special code for the first frame.
