Adds a dependent config flag 'interintra' to turn on/off interintra
modes altogether.
Adds a dependent config flag 'wedge' to turn on/off wedge compound
for both interinter and interintra.

Adds another macro to change wedge predictors to use
only 0, 1/2, or 1 weights.

From now, use
--enable-ext-inter --enable-wedge --enable-interintra to get the
same behavior as the old --enable-ext-inter.

This filter was temporarily removed due to test failures.
This patch reintroduces the filter and fixes two bugs:

* The test cases would occasionally segfault on x86, since
  the highbd filter requires its inputs to be aligned to
  16 bytes. This will always be true when used on real videos,
  so adjust the test cases to match.

* The function calc_block was incorrect for bit_depth > 8,
  due to passing an incorrect argument to _mm_srl_epi32().
  This was the cause of the original test failures.

Enabling SEPARATE_GLOBAL_MOTION will remove the ability for
a block that uses zeromv with global motion to pick warped_causal
or obmc_causal as the motion mode. When this is enabled there is:

0.05% drop on lowres for global + warped enabled
0.15% drop on midres for global + warped enabled

0.12% drop on lowres with global + motion var enabled
0.07% drop on midres with global + motion var enabled
No performance change for global, warped, or motion var individually.

This fix was motivated by a code generation bug in g++ on arm, but it
seems a good idea generally to disable these unit tests if we're not
compiling with optimisations, since the code tested is only intended
to be used as inlined functions, and while it's possible to compile
without optimisations, the tests become somewhat half-hearted since
there are workarounds when there's no inlining (such as for
instrinsics requiring immediate values), so the tests would partly
test code that wont be used anyway.

  - Dering strength can now be 0, 1 or 2 bits per block

Replaces the int64 and int32 divisions in least-squares and
gamma or delta computation with a mechanism that decomposes
the divisor D such that 1/D = y * 2^-k where y is obtained
from a lookup table indexed by 8 highest bits of the difference
D - 2^floor(log2(D)). The main complexity is now only from
computing this decomposition, which is essentially equivalent
to finding floor(log2(D)) (position of highest
bit in a 64-bit integer).

Also includes an out of memory bug fix and some cleanups.

This draft version only pass compiling check, it's not working yet.

The following goal is to use new coding system when doing bitstream
packing but keep old coding system in RD loop.

This commit implements support for twopass encoding using the xiphrc
experimental rate control system. Most of the code and logic comes
from the theora project encoder.

Currently support is limited to the bitrate targeting mode of the
rate control system and while it does visibly improve quality and does
bring rate closer to the target than the one pass mode there's still
tuning and bug fixing to be done.

Doing tokenize in the last step of RD loop and then doing packing
tokens in bitstream packing phase is hard for debugging.

Therefore, we create a frame-level buffer to store the txfm coeffs
from the reconstruction in RD loop and then in bitstream packing
phase, we can code the txfm coeffs directly.

Fixes some rd-debug mismatches coding cat6 tokens with tx size < 32x32.
For these tokens the high extrabits are elided during tokenization and
detokenization, but the rd cost was computed with the old tables from
VP9 where these high extrabits are always coded.
