In a previous commit, the duplicate of headerfile defaultcoefcounts.h
was identified. This commit updates the .mk file to ensure configure
and make works properly for all platforms.

The maximum psnr has a marginal impact on the overall output in high
quality encodings, the change will make sure the psnr output to be
consistent with encoder internal stats.

https://gerrit.chromium.org/gerrit/#change,17319 fixes cost estimating
to take skip_eob into account. No quality difference seen on derf set
tests, but about .4% gain on STD_HD set.

Change-Id: I4159ff365953598d9c9bc3ecacfb5c5f4a315b45

This gives a modest gain on derf overall, although at low bitrates the
cost is still too high, so this can be improved further.

Patch 2. Re-base and fix 80 column issues

The commit changed to compute UV intra RD estimates for 4x4 and 8x8
separately to be used in mode decision for MB modes associated with
the appropriate transform size respectively. Now finally after many
other changes related 8x8 quantizer zbin boost and zbin_mode_boost,
this change overall helps the HD(with 8x8) by around ~.13%.
(avg .13%  glb .13% ssim .17%)

The commit also has a few changes for eliminating compiler warnings.

Change-Id: Ibab35dad44820c87e6b44799c66f8d519cc37344

The commit added the correct Zbin_mode_boost initialization based on
Intra Mode before using rate distortion to pick UV intra mode.

The commit fixed a problem where 8x8 regular quantizer was using the
4x4 zbinboost lookup table that only has 16 entries at each Q. The
commit assigned a uniform zbin boost value for all cases that there
are more than 16 consective zeros. The change only affects MBs using
8x8 transform. The fix has a slightly positive impact on quality.

Test results:

(avg psnr: .26% glb psnr: .21% ssim: .28%)

Results on cif size clip are also positive even though gain is smaller

This is the first patch for refactoring of the code related to
high-precision mv, so that 1/4 and 1/8 pel motion vectors can
co-exist in the same bit-stream by use of a frame level flag.
The current patch works fine for only use of 1/4th and
only use of 1/8th pel mv, but there are some issues with the
mode switching in between. Subsequent patches on this change Id
will fix the remaining issues.

Patch 2: Adds fixes to make sure that multiple mv precisions can
co-exist in the bit-stream. Frame level switching has been tested
to work correctly.

Patch 3: Fixes lines exceeding 80 char

Patch 4:
http://www.corp.google.com/~debargha/vp8_results/enhinterp.html

Results on derf after ssse3 bugfix, compared to everything
enabled but the 8-tap, 1/8-subpel and 1/16-subpel uv. Overall the
gains are about 3% now. Hopefully there are no more bugs lingering.
Apparently the sse3 bug affected the quartel subpel results more than
the eighth pel ones (which is understandabale because one bad predictor
due to the bug, matters less if there are a lot more subpel options
available as in the 1/8 subpel case).
The results in the 4th column correspond to the current settings.
The first two columns correspond to two settings of adaptive switching
of the 1/4 or 1/8 subpel mode based on initial Q estimate. These
do not work as good as just using 1/8 all the time yet.

The "update" variable was used as a flag in coef_prob update dry run
that tests if a frame should encodes update at all. The wrong init
value forced the update happening always. fixing this has a minor
improvement in low bit rate situation when 8x8 transform is allowed.

The Lagrangian interpolation filter is maximally flat in the
passband. There is non-trivial improvement with the hd set, while
for derf the results are virtually unchanged.
See:
http://www.corp.google.com/~debargha/vp8_results/enhinterpn.html (derf)
http://www.corp.google.com/~debargha/vp8_results/enhinterpn_hd.html (HD)

Patch 2: Updated the results for derf in the html above to use the
new baseline. There is still about 4% improvement. Will update the
hd baseline later (since it takes 9 hours to run on my machine)

Patch 3: By mistake the default filter was left at 60 - should be 0
to use the new interpolation filter.
