- Use Makefile to control the build for highbd_fwd_txfm_sse4.c.
- Fixed hybrid transform (HT) types due to recent update.
- Added new unit test cases for highbd HT.

Uses 15 frames instead of 30. Also only test speed 0 for VP10.

This has been ported under ext_partition_types because it is due
to be combined with the coding_unit_size experiment which is
already being ported under ext_partition

Merge the functions that generate prediction by above/left predictors
for the encoder and the decoder.

Decompose choose_tx_size_from_rd into three functions that determine
the transform coding rd at different stages. Besides the original
function, txfm_yrd() calculates the rd for fixed size and type.
choose_tx_size_fix_type() fixes the type and searches for the size.
It can enable other experiments to do restricted tx searches so as to
reduce the impact on speed.
Similar refactoring is done for select_tx_type_yrd() in VAR_TX.

Performance change in baseline is trivial:
0.014/0.001/-0.020 for lowres/midres/hdres.

This allows sharing more code paths with the rest of the code an allows
for easier compatibility with the other experiments.

Makes a set of 16 transforms total, adding all 1D
combinations of ADST and FlipADST, and removng all DST
transforms.

lowres, midres both improve by about 0.1% and hdres by
-0.378% in BDRATE but with fewer transforms that are also
simpler.

Further experiments to continue later.

Not getting good results for this feature, will try again
when transforms are frozen.

This buffered ANS coder supports coding the symbols in forward (decode)
order. Rather than windowing or growing the buffer, right now this
coder merely asserts that the buffer will never overflow.

This approach should allow ANS to be used as a drop in replacement for
other entropy coders rather than requiring complicated reversal logic
throughout the codebase.
