Mark functions in findnearmv.h, invtrans.h and setupintrarecon.h
with INLINE.
Hide function in postproc.h behind the same #if as it's callers.

Allow for option to apply spatial blur for temporal
denoising, under the aggressive denoising mode.

Set the proper number of mb_rows/cols.
Also remove warnings (unused variable) when configured with temporal-denoising disabled.

Added macro to conditionally compile some of the
post-processing functions only when CONFIG_POSTPROC
is defined.
This was causing the build for the generic-gnu target
to fail.

This patch fixed WebRTC Issue 3020: "Uninit error at
vp8_mbpost_proc_down_xmm". The first 8 values in d were not initialized,
but was accessed. This patch fixed c code as well as mmx and sse2 code.

Adding -Wshadow to CFLAGS generated a bunch of warnings. This patch
removes these warnings.

When error concealment is enabled, it swaps the mi and prev_mi ptrs after
each frame is decoded. The postproc uses the mi ptr for the mode info context.
Now the postproc will use the correct mode info context.

If the threshold(limits) <= 0, skipped filtering and copied the
frame directly. Also, fixed memory allocation checking.

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.

Adjusts some of the qualification thresholds in mfqe to eliminate
artifacts due to wrong decisions. Besides, a new qualification
criteria is used to disable mfqe if the quality of the previous
frame is itself not too good.

The function vp8_post_proc_down_and_across_c takes the
stride of both the src and dst images as parameters, but
assumes that they are the same.
I modified the code to use the correct strides, as the
assembler versions of these functions do.

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.

We can get rid of all remaining global initializers now:
vp8_scale_machine_specific_config()
vp8_initialize()
vp8dx_initialize()

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.

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%

As an optimization some architectures use the max_sad argument to break
out early from the SAD. Pass in INT_MAX instead of 0 to prevent this.

MFQE postproc crashed with stream dimensions not a multiple of 16.
The buffer was memset unconditionally, so if the buffer allocation
fails we end up trying to write to NULL.
This patch traps an allocation failure with vpx_internal_error(),
and aligns the buffer dimensions to what vp8_yv12_alloc_frame_buffer()
expects.

Commit 892e23a5b introduced support for the VP8D_GET_LAST_REF_USED,
but missed the mapping of the control id to the underlying function,
so it was unavailable to applications.
In addition, the underlying function vp8_references_buffer() is
moved from common/postproc.c to decoder/onyxd_if.c as postproc.c is
not built in all configurations.

Makes the thresholds for the multiframe quality enhancement module
depend on the difference between the base quantizers. Also modifies
the mixing function to weigh the current low quality frame less if
the difference in quantizer is large. With the above modifications
mfqe works well for both scalable patterns as well as low quality
key frames.
