Allow for an option to selectively apply the deblocking loop filter to the denoised
raw block, based on the denoised state (no-filter, filter with zero motion, or filter with non-zero motion)
of the current block and its upper and left denoised block.
This helps to reduce some blocking artifacts from the motion-compensated denoising.

As a side-effect, the max_sad check is removed from the
C-implementation of VP8, for consistency with VP9, and to
ensure that the SAD tests common to VP8/VP9 pass.
That will make the VP8 C implementation of sad a little slower
but given that is rarely used in practice, the impact will be
minimal.

predict_d has become canonical. Remove previous helper function.
Disable ARM assembly pending update.

SAD returns unsigned values. Make all the declarations the same.
Remove bestsad initialization and check. It is always set to the
result of a SAD call so it will never remain UINT_MAX
Use ja instead of jg to test unsigned comparison instead of signed.
Update test.

Allows building the library with the gcc -pedantic option, for improved
portabilty. In particular, this commit removes usage of C99/C++ style
single-line comments and dynamic struct initializers. This is a
continuation of the work done in commit 97b766a46, which removed most
of these warnings for decode only builds.

This extends the denoiser to work for temporally scalable
coding.
I believe this also fixes a very rare but really bad bug in the original
implementation.

RD costs were local to MACROBLOCK data and had to be copied all the
time to each thread's MACROBLOCK data. Tables moved to a common place
and only pointers are setup for each encoding thread.
vp8_cost_tokens() generates 'int' costs so changed all types to be
int (i.e. removed unsigned).
NOTE: Could do some more cleaning in vp8cx_init_mbrthread_data().

This issue likely doesn't appear in the unmodified encoder, but
sufficient hacking on the mode selection loop can expose it.

Coefficient costing failed to take account of the first branch
being skipped ( 0 vs eob) if the previous token is 0.
Fixed rd to account for slightly increased token cost & cleaned up
warning message

Reworked the code to use vp8_build_intra_predictors_mby_s,
vp8_intra_prediction_down_copy, and vp8_intra4x4_predict_d_c
functions instead. vp8_intra4x4_predict_d_c is a decoder-only
version of vp8_intra4x4_predict. Future commits will fix this
code duplication.
