- For experiment EXT_INTERP under high bit depth.
- Add unit test to verify bit-exact.
- Speed performance improvement:
On Xeon E5-2680, park_joy_1080p_12.y4m, 50 frames, encoding time
drops from 6682503 ms to 5390270 ms.

This commit makes the filter extension in highbd aware of the
dual filter and ext-interp experiments to prevent enc/dec mismatch
when both experiments are turned on.

The amount of border extension needed in the first stage inter
filtering is decided by the length of the second stage filter
kernel.

This commit fixes the compiler error in high bit-depth inter
predictor when dual filter type experiment is turned on.

Make the bit-stream level support per direction filter type coding
for motion compensated reference.

If --enable-ext-partition is used at build time, the superblock size
(sometimes also referred to as coding unit (CU) size) is extended to
128x128 pixels.
Change-Id: Ie09cec6b7e8d765b7555ff5d80974aab60803f3a
Includes various cosmetic changes and refactoring including
naming the sharp filters differently (since they are no longer
8-tap).

Priviously, we do 12-tap interpolation even there is no sub pixel,
This could cause a bug becuase decoder doesn't extend border when there
is no sub pixel. In this situation, if we still do interpolation, we
will access the border extension which doesn't exist and cause a
memory error
