Also use int instead of int64_t since sf->exhaustive_searches_thresh is
an int and we only make it smaller.

This experiment complexifies DSP function dispatch, without bringing
any real value (it's non-normative arbitrary behaviour).
Moreover, it only has an effect on obsolete transforms, the new ones
don't implement this mechanism.

When compiled with --disable-lowbitdepth, the decoder uses the generic
16-bit operating path, regardless of the input video profile.
The encoder should also use the generic 16-bit operating path if the
low-bitdepth operating path has been disabled at build time.

Changes on BD-Rate are:

Additionally, BD-Rate change by daala-dist in enforced MSE mode
which can show the correctness of implementation is

This changes the behavior of the ext-inter compound modes
as follows:
* NEAREST_NEARESTMV, NEAR_NEARMV, NEW_NEWMV, ZERO_ZEROMV
  work the same as the corresponding compound modes without
  ext-inter
* NEAREST_NEWMV and NEW_NEARESTMV keep their current behavior,
  which is to use the first ref-mv candidate pair for their
  particular reference frames
* NEAR_NEWMV and NEW_NEARMV select between the second, third,
  and fourth candidate pairs.
* NEAREST_NEARMV and NEAR_NEARESTMV use the first candidate
  pair for the NEAREST component and the second, third, or
  fourth candidate pair for the NEAR component.

Also do some minor refactoring and fix compile errors
with --enable-ext-inter --disable-ref-mv

Transmit palette colors with delta encoding.
Coding gain on scrren_content testset:
overall 0.67%  keyframe 1.37%

Change-Id: I72ce9061dfddf933e9f7530f069955afcb07edf8

Added 2 tile encoding modes:
TILE_NORMAL mode supports the large-scale tile coding up to 1024 x 1024
tiles;
TILE_VR mode supports the large-scale tile coding and also the decoding
of a single tile.

TILE_NORMAL mode allows the non-vr content to be encoded in multiple tiles
without using the coding tool that are designed for vr applications.

The bitstream_queue_pop and bitstream_queue_push functions were
implemented twice each, one implementation for CONFIG_DAALA_EC being set
and for it not being set. This could cause issues with debugging since
there's two potential paths, meaning breakpoints and edits need to be
inserted twice.

The functions were already minimally different, so this patch merges the
implementation pairs to simplify the code.

* Refactor write_inter_mode and cost_mv_ref slightly

* In handle_inter_mode: When discount_newmv_test returns 1,
  ext-inter is enabled, and we're costing up a compound mode,
  we would previously call cost_mv_ref with mode=NEARESTMV and
  comp_pred=1. But this is inconsistent when ext-inter is enabled!

  Fix this by changing the behaviour of cost_mv_ref to (effectively)
  derive comp_pred from the mode passed in, and switch to
  mode=NEAREST_NEARESTMV in the above case.

* Fix incorrect motion vector costing for some compound modes

* Fix a case where compound blocks were mis-costed. This primarily
  affects ext-inter *without* wedge or compound-segment enabled,
  but should still have some small impact when those experiments
  are enabled.

  The cause of this is that we only spend bits to send the
  interinter compound type if is_any_masked_compound_used(bsize)
  returns true. But the rdopt loop forgot to check this condition
  in one case.

Change the adjustment range from [50% ... 300%] to [25% ... 100%].
Adjustments above 100% were very rare, and capping the adjustment at
100% adds SIMD optimisation opportunities.  And lowering the other end
to 25% seems to help compresson slightly.

kMinCompressedSize was defined as a global constant, so it
was exported by default and possibly causing duplicate
symbol issues for applications. In particular, libvpx also
exports this symbol.

Instead, move the definition into the only function which
references is. As a local variable it is hidden from the
linker and not part of the global symbol table.
