ceb5174205 Segment Feature Signaling
Plumbing for tuning new segment features on and off.

1c24442a07 Change to segment_feature_data[][] structure.
This data structure is  now [Segment ID][Features]
rather than [Features][Segment_ID]

I propose as a separate modification to make the experimental
bit stream reflect this such that all the features for a segment
are coded together.

dfbc61f3ab Segment Features:
Some basic plumbing added for a range of segment level features.
MB_LVL_* changed to SEG_LVL_* to better reflect meaning.

a04ed0e8f3 fix sharpness bug and clean up
sharpness was not recalculated in vp8cx_pick_filter_level_fast

remove last_filter_type. all values are calculated, don't need to update
the lfi data when it changes.

always use cm->sharpness_level. the extra indirection was annoying.

don't track last frame_type or sharpness_level manually. frame type
only matters for motion search and sharpness_level is taken care of in
frame_init

move function declarations to their proper header

622958449b New loop filter interface
Separate simple filter with reduced no. of parameters.
MB filter level picking based on precalculated table. Level table updated for
each frame. Inside and edge limits precalculated and updated just when
sharpness changes. HEV threshhold is constant.
ARM targets use scalars and others vectors.

Change works only with --target=generic-gnu
All other targets have to be updated!

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

3698c1f620 Removed dc_diff from MB_MODE_INFO
The dc_diff flag is used to skip loopfiltering.  Instead
of setting this flag in the decoder/encoder, we now check
for this condition in the loopfilter.

bf5f585b0d Make vp8_adjust_mb_lf_value return the updated value rather than
manipulating it in situ via a pointer.

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.

c2140b8af1 Use WebM in copyright notice for consistency
Changes 'The VP8 project' to 'The WebM project', for consistency
with other webmproject.org repositories.

Fixes issue #97.

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.
