If configured with --enable-ext-tile, the codec uses an alternative
tile coding syntax in the bitstream. Changes include::
 - The maximum number of tile rows and columns is extended to 1024
   each.
 - The minimum tile width/height is 64 pixels (1 superblock).
 - A tile copy mode is added where a tile directly reuse the coded
   data of a previous tile
 - The meaning of the tile-columns and tile-rows codec parameters are
   overloaded to mean tile-width and tile-height in units of 64
   pixels.
 - All tiles should now be independent, including rows within the
   same columns, so large scale parallel, or independent decoding is
   possible.
 - vpxdec also gained the options to decode only a particular tile,
   tile row, or tile column.

Changes without --enable-ext-tile:
 - All tiles should now be independent, including rows within the
   same columns, so large scale parallel, or independent decoding is
   possible.
 - vpxenc default tile configuration changed to use 1 tile column.

- 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.

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

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.
