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.

9c2ca8c1ca Allowing the mfqe post-processing filter to be used in conjunction
with deblock or demacroblock filters. When --mfqe is used together
with --demacroblock or --deblock, mfqe is applied first and then
demacroblock/deblock is applied to the mfqe result.

19987dcbfa Faster vp8_default_coef_probs
Copies from a generated table instead of building the
default coeff probabilities during runtime.

deca8cfc44 Fixed initialization of frame buffer ref counters
Only the first frame buffer ref counter was being initialized
because the index was fixed at 0 rather than using i.

d04f852368 Adding error-concealment to the decoder.
The error-concealer is plugged in after any motion vectors have been
decoded. It tries to estimate any missing motion vectors from the
motion vectors of the previous frame. Intra blocks with missing
residual are replaced with inter blocks with estimated motion vectors.

This feature was developed in a separate sandbox
(sandbox/holmer/error-concealment).

01527e743f remove simpler_lpf
the decision to run the regular or simple loopfilter is made outside the
function and managed with pointers

stop tracking the option in two places. use filter_type exclusively

43464e94ed Do not copy data between encoder reference buffers.
Golden and ALT reference buffers were refreshed by copying from
the new buffer. Replaced this by index manipulation.
Also moved all the reference frame updates to one function for
easier tracking.

429dc676b1 Increase static linkage, remove unused functions
A large number of functions were defined with external linkage, even
though they were only used from within one file. This patch changes
their linkage to static and removes the vp8_ prefix from their names,
which should make it more obvious to the reader that the function is
contained within the current translation unit. Functions that were
not referenced were removed.

These symbols were identified by:

  $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \
    | sort | grep '^ *1 '

c4d7e5e67e Eliminate more warnings.
This eliminates a large set of warnings exposed by the Mozilla build
 system (Use of C++ comments in ISO C90 source, commas at the end of
 enum lists, a couple incomplete initializers, and signed/unsigned
 comparisons).
It also eliminates many (but not all) of the warnings expose by newer
 GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
 without checking the return values).
There are a few spurious warnings left on my system:

../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
 uninitialized in this function
gcc seems to be unable to figure out that the value shortcut doesn't
 change between the two if blocks that test it here.

../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
 expression >= 0 is always true
../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
 expression >= 0 is always true
This is true, so far as it goes, but it's comparing against an enum, and the C
 standard does not mandate that enums be unsigned, so the checks can't be
 removed.

e85e631504 Changed above and left context data layout
The main reason for the change was to reduce cycles in the token
decoder. (~1.5% gain for 32 bit)  This layout should be more
cache friendly.

As a result of this change, the encoder had to be updated.

7a8e0a2935 Fix harmless off-by-1 error.
The memory being zeroed in vp8_update_mode_info_border() was just
 allocated with calloc, and so the entire function is actually
 redundant, but it should be made correct in case someone expects
 it to actually work in the future.

99f46d62d9 Moved gf_active code to encoder only
The gf_active code is only used by the encoder, so it was moved from
common and decoder.

0ce3901282 Swap alt/gold/new/last frame buffer ptrs instead of copying.
At the end of the decode, frame buffers were being copied.
The frames are not updated after the copy, they are just
for reference on later frames.  This change allows multiple
references to the same frame buffer instead of copying it.

Changes needed to be made to the encoder to handle this.  The
encoder is still doing frame buffer copies in similar places
where pointer reference could be done.

1df0314e7b configure: remove HAVE_CONFIG_H
This doesn't play well with autotools, and the preprocessor magic is
confusing and unhelpful in the vp8-only context.
