06fce6b640 vp8: Update to the adaptive denoising mode.
Allow for option to apply spatial blur for temporal
denoising, under the aggressive denoising mode.

f6886c4b93 post-proc: fix 0 or negative threshold handling
If the threshold(limits) <= 0, skipped filtering and copied the
frame directly. Also, fixed memory allocation checking.

4c53bacce4 post-proc: deblock filter optimization
1. Algorithm modification:
Instead of having same filter threshold for a whole frame, now we
allow the thresholds to be adjusted for each macroblock. In current
implementation, to avoid excessive blur on background as reported
in issue480(http://code.google.com/p/webm/issues/detail?id=480), we
reduce the thresholds for skipped macroblocks.

2. SSE2 optimization:
As started in issue479(http://code.google.com/p/webm/issues/detail?id=479),
the filter calculation was adjusted for better performance. The c
code was also modified accordingly. This made the deblock filter
2x faster, and the decoder was 1.2x faster overall.

Next, the demacroblock filter will be modified similarly.

66ba79f5fb Miscellaneous changes in mfqe and postproc modules
Adds logic to disable mfqe for the first frame after a configuration
change such as change in resolution. Also adds some missing
if CONFIG_POSTPROC macro checks.

fd903902ef RFC: Reorganize MFQE loops
Break MFQE code into it's own file.

It is currently only valid for 16x16 and 8x8 Y blocks. It also filters
4x4 U/V blocks.

Refactor filtering and add associated assembly. Limited test cases show
--mfqe introduces a penalty of ~20% with HD content. The assembly
reduces the penalty to ~15%

87aa846b47 Multiframe quality enhancement postprocessing
Adds a multiframe postprocessing module to enhance the quality of
certain frames that are coded at lower quality than preceding frames.
The module can be invoked from the commandline by use of the --mfqe
option, and will be most beneficial for enhancing the quality of
frames decoded using scalable patterns.

Uses the vp8_variance_var16x16 and vp8_variance_sad16x16 function
pointers to compute SAD and Variance of blocks.

647df00f30 postproc : Re-work posproc calling to allow more flags.
Debugging in postproc needs more flags to allow for specific
block types to be turned on or off in the visualizations.

Must be enabled with --enable-postproc-visualizer during
configuration time.

0e7b60617f postproc : Update visualizations.
Change color reference frame to blend the macro block edge.
This helps with layering of visualizations.

Add block coloring for intra prediction modes.

a097e18964 postproc: Tweaks to line drawing and blending.
Turned down the blending level to make colored blocks obscure
the video less.
Not blending the entire block to give distinction to macro
block edges.
Added configuration so that macro block blending function can
be optimized.
Change to constrain line as to when dx and dy are computed.
Now draw two lines to form an arrow.

94c52e4da8 cosmetics: trim trailing whitespace
When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.
