This commit added the ability to accumulate the coef stats across
different encodings using an intermediate binary stats files. The
accumulation happens only the binary stats file exists in current
directory. The encoder needs to be built with "ENTROPY_STATS" to
allow the output. The commit also fixed a few formating issues in
output stats file.

Changes to calculation of sr_coded_error to include 0,0 case.
Experimental use of sr_coded_error in calculating correction factor
for estimating the allowable Q range.
Reinstated some code needed for calculating section_intra_rating.
Add flash detection in calculation of KF boost
Increased tolerance in testing candidate key frames (needed with
longer motion search as this tends to slightly increase inter %.
Zbin changes for 8x8.
Other minor adjustments, refactoring and bug fixes.
Reinstated some motion break out clauses in boost loop
as their removal hurt a few 50fps clips badly in the std set.
It may be possible to remove them again later if a better way
can be found of preventing overly long gf intervals.

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.

Frame dropping decision is made by evaluating both current frame
and next frame's buffer_level. If both buffer_levels are less
than drop_mark, next frame is dropped. When frame dropping is
over, namely, buffer_level becomes normal again, we need to
reset decimation_count to 0.

The logic for spatial resizing is done after the Q is selected for the
frame. This causes a problem that the Q we select for the (resized)
key frame may be based on a different resolution than the frame we
will encode.
This fix is to ensure that, when resize is on, the selected Q is still
based on the resolution of the frame to be encoded.

The change in assembly offset files to define values as const int broke
Windows build, because the variables are stored in .rdata section instead
of .data section.
This CL changes the integer peeking from .data to .rdata.

This change is to allow obj_int_extract to extract all integers
in the data segment. With the const keyword these variables are
forced into the .rodata segment even for zero variable value.
We had a problem before that zero valueed variables would get
assigned to BSS segment that fooled obj_int_extract to give
incorrect values.

Update the Visual Studio builds to support the new monolithic unit
test binary.
Includes minor semi-cosmetic refactoring of solution.mk, as the
%vpx.vcproj match is no longer appropriate given the test_libvpx
target.

Variables m & mi were being dereferenced when they might
hold invalid values.
The fix is simply to move these dereferences to after the
point at which mb_row and mb_col are tested for validity.

Compares the sum of differences between the input block and the averaged
block. If they differ too much the block will not be filtered. Negligible
perfomance hit.

Add PRIVATE macro for adding private_extern directive for yasm
to hide global symbols. This is only enabled if -DCHROMIUM is used
with YASM.
Also fixed a small problem with rtcd_defs.sh to guard TEMPORAL_DENOISING.

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.

This fix addresses some problems with very complex clips like
handling of flashes on clips like crew (which was made worse
by an earlier patch (derf and std-hd)).
Most clips a small effect but some between 1 & 2%
Derf +0.039, +0.211%
YT +0.042, +0.083%

Removed the local scaling factor est_max_qcorrection_factor

anyway)
Cap range of total correction factor.
Slight change to break out case to turn off arf.
