Arild Fuldseth 7acfabbc40 7-bit interpolation filters 
Purpose:
-Reduce dynamic range of interpolation filter coefficents from 8
bits to 7 bits.
-Inner product for 8-bit input data can be stored in a 16-bit signed
integer.

Impact on compression efficiency:
-Marginal improvement, typically less than 0.5% BDR.

--cpu-used=4 -p 1 --end-usage=q --cq-level=40 --tile-columns=0 --tile-rows=0

Ran some manual sanity checks:
- Verified that the automatically generated encodings match the
  hand-written encodings before the patch.
- Verified that the encoded bitstream before/after this patch is
  identical.

Jingning Han 7f76d4763d Prevent potential token buffer overflow in format 444 
For a 16x16 pixel block, one needs to allocate 16x16 coefficient
tokens, plus up to 16 eob tokens, per plane. This commit increases
the token allocation size to cover the case where all the transform
blocks are of size 4x4 in format 444.
