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.

Patch https://aomedia-review.googlesource.com/c/8387/ introduced
some bugs into the self-guided filter correctness test. One bug
was fixed in https://aomedia-review.googlesource.com/c/8445/ ,
but another surfaced while developing
https://aomedia-review.googlesource.com/c/8480/

This patch tidies up the relevant code to make it clearer,
and should fix the remaining bug(s).

- 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.

This ports the wx-widgets stream analyzer from Daala to AV1.
Currently, this supports playback, zooming, and printing bit accounting
 statistics to stdout.
The configure script does not yet build the analyzer, to compile it:

 libaom.a `wx-config --cppflags` `wx-config --libs` -o analyzer

The interpolation filter search used to be performed in a code block in
handle_inter_mode(). This change breaks that code out into its own
function to reduce the length of handle_inter_mode and ecapsulate its
functionality, making both functions more readable.

Attention has been paid to make as many arguments constants as can be.

The variable "use_hbd" was defined but not used in four places in the
codebase. The warning that it wasn't used was missed by Jenkins
because it only tries one experimental flag at a time, but these
definitions were inside nested experimental flag conditions. Both
CONFIG_WARPED_MOTION and CONFIG_AOM_HIGHBITDEPTH had to be set for the
variables to be defined.

This patch deletes the unused definitions to remove the unused variable
warnings when the AV1 encoder and/or decoder are built with warped
motion and high bitdepth configured.
