This required moving the CDEF and lr signaling in the
uncompressed header to after segmentation is signaled.

The all_lossless logic was factored out into onyxc_int.h.

When EC_ADAPT is enabled, this patch uses the adapted CDF after
 encoding the entire frame to compute the non-adapted costs that are
 used in RDO decision making when coding the following frame.
Future patches will update these costs periodically while coding the
 frame to keep them in sync with the actual rates used when coding the
 symbols with the adapted CDF.

The encoder and decoder will now use the 16-bit (high-bitdepth)
coding path, regardless of the encoding profile.

This is a step towards the removal of the 8-bit (low-bitdepth)
coding path (which remains compile-checked at the moment).

When computing CFL's prediction block level DC_PRED,
We can't assume that the neighbor will use the same
transform size. As such, we don't know what pixels
are available outside of the frame. A simple
solution is to stop computing DC_PRED at the block
boundary.

The function cfl_compute_parameters is added and contains the logic
related to building the CfL context parameters. As such, many cfl
functions can now be encapsulated inside of cfl.c and not exposed to the
rest of AV1.

This also allows for supplemental asserts that validate that the CfL
context is properly built.

This tool is a gadget for offline probability training.

A binary executable aom_entropy_optimizer will be generated in
tools/. It parses a binary file consisting of counts written in
the format of FRAME_COUNTS in entropymode.h, and computes the
optimized probability table, which will be written to a new c file
optimized_probs.c using the format in entropymode.c.

Command line:
./aom_entropy_optimizer [directory of the count file]

The input file can be either be generated from a single run by
turning on entropy_stats experiment(counts are accumulated from
frame to frame, and finally written to counts.stt), or be collected
at a larger scale, at which a python script (will be provided soon)
can be used to aggregate multiple stats output.

Optimization for initial CDFs will be also supported later.
