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.

this change unifies the intra prediction angles so that 8x8 block has
the same number of angles and angle steps as 16x16 and 32x32 blocks.
the benefit is that HW implementation can have the same logic to
handle all block sizes. otherwise, prediction angles for 8x8 is
different from other block sizes, which requies special logic.

Hoists the iCDF conversion outside of the daala code.
We directly store 32768 - cdf[i] in each cdf, to avoid having to
convert the whole array every time a symbol is coded.

This works with ec_multisymbol, new_tokenset, and ec_adapt.

Compared to Change-Id Idbbd3743e9189146cb519d5b984bdabd69e3f4c0,
this improves decoder runtimes by 1.15% at QP=55 and 2.64% at
QP=20.

The overall slowdown of ec_smallmul is now 0.12% at QP=55 and
0.44% at QP=20.

Encoder output should not change, and all streams should remain
decodable without decoder changes.

The "good" speed levels are universally better than the "rt" ones,
running faster to achieve the same quality.

rt mode also turned off alt refs and lag-in-frames, but these
are still accessible separately (and the low latency test case
explicitly sets them).

Some features were used by the rt scale and not the good scale.
Two additional "good" levels, 7 and 8, were added to accomidate
these features and not reduce test coverage.

If daala_ec is disabled while bistream_debug is enabled, decodeframe.c

DC only idct cases will occur more frequently at lower bit rates.
