The function is_rect_tx previously was only defined when
both ext-tx and rect-tx are enabled together. This function
needs to be defined when rect-tx is enabled alone to fix
failing asserts.

Frame Super-Resolution is an experiment currently under development.
This commit just adds an experimental flag for it.
The goal of the experiment is to compress a downsampled version of a
frame instead of the full resolution one when bandwidth is limited. The
decoder will need to upsample and filter the frame it recieves after
decoding. It is thought that this will result in a visually superior
result in low bandwidth scenarios.

The initial CDF for each frame is stored in
the frame context. CDFs for actual coding are
stored in the tile structures, and these are
what get adapted. The initial CDF is replaced
by an average CDF derived from these tile CDFs.
This is carried forward to future frames when
backward adaptation is on.
CDFs are no longer set from the 8 bit probabilities
in backwards adaptation.
For now, 8 bit probabilities are maintained for
use in the encoder and for symbols which do not
have a CDF.

One codepath originally skipped a function which forks between
gm prediction and regular inter prediction. This change fixes this
for both high bit depth and regular bit depth.

Generated using av1_tree_to_cdf().
Note: These are currently overwritten by CDFs generated from default
probability tables. But they will be used eventually when we remove the
default probability tables.

This reverts commit 48c10c7d91.
Reason for revert: this incorrectly detects feenableexcept for
i686-w64-mingw32 (at least), causing the link to fail

The addition of a 2D array to the HandleInterModeArgs struct means there
is now a non-optional member in the opt_args struct passed to
handle_inter_mode and its child functions. Since opt_args no longer
consists solely of optional members I've renamed it args.

The bitstream has now changed as we enabled ALT_INTRA by default now, so
need to update the golden MD5.

Two 2D arrays were passed to HandleInterMode and not used elsewhere.
One has been added to the HandleInterModeArgs struct to
simplify handle_inter_mode's signature and the the calling function.
The other has been unread since commit
beacb3ff79. That patch removed the
"skip_txfm optimization" but left the single_skippable array in place,
even though it was no longer read. Since the array's only usage has been
removed, this patch removes the variable outright.

This keeps track of how many calls have been made
to read symbols or bits. A given syntax element
may make multiple calls to symbol decoding functions,
and these variables keep track of the entropy
decoding engine throughput.

Adds an option controlled by a macro to replace one of
the guided filters in the self-guided tool with a simple
bandpass filtered version generated with a 3x3 kernel.
By default the macro USE_HIGHPASS_IN_SGRPROJ is 0 (turned
off), that defaults us to the dual self-guided filter.
When the macro is turned on, the larger radius guided
filter is replaced by a simpler filter that is much faster.
Results (if USE_HIGHPASS_IN_SGRPROJ is on vs. off):
lowres: performance drop by +0.14% (BDRATE)
midres: performance drop by +0.27% (BDRATE)
Further experiments on this variation of guided filters is
pending.

this change added back the original 15 tap filter from VP9 back into
the parallel_deblocking experiment. when transform size of both blocks
along the edge is greater than 16x16, 15 tap filter is used.

- Use the FindwxWidgets (the cmake module) to detect library
flags and handle include paths.
- Update target to link in the libs located by FindwxWidgets.
- Enable CONFIG_INSPECTION and warn at generation time when it's
not present and CONFIG_ANALYZER is enabled.

Cosmetic change that moves the declaration of mbmi at the beginning of
the function. This simplifies access and removes the need for
(void)mbmi.

Apart from being inefficient, the floating point operation log2()
was resulting in an assertion failure due to an unrelated floating
point exception that happens earlier.
Related: update the MD5s in test_intra_pred_speed to fix that failure
too.
