5e56bbe09a AnimEncoder API: Remove AnimEncoderFrameOptions. 
We only need config now, so this struct is not needed.

b902c3ea50 AnimEncoder API: GenerateCandidates bugfix. 
As 'curr_canvas_mod' is being modified during calls to IncreaseTransparency()
and FlattenSimilarBlocks(), GetSubRect() should get the sub-frame from
'curr_canvas_mod' as well.

Earlier, GetSubRect() was computed from 'curr_canvas', so modifying
'curr_canvas_mod' had no effect on encoding.

ef3c39bbd2 AnimEncoder API: Compute change rectangle for first frame too. 
Earlier, we were always using full canvas for first frame.

eec423abe9 AnimEncoder API: In Assemble(), always set animation parameters. 
We set the parameters even if there is just one frame. This is to make sure
assembly is correct even if single frame animation is NOT converted to a full
frame later.

ae1c046e12 AnimEncoder lib cleanup: prev to prev canvas not needed. 
Given that we decided to only handle frame disposal for output WebP
internally,
only current and previous canvas need to be maintained.

4b997ae46d WebPAnimEncoder API: Header and implementation 
A separate API to generate animated WebP images.
It will eventually replace the internal gif2webp_util methods.

Also: update makefiles.

a437694a17 multi-thread fix: lock each entry points with a static var 
we compare the current VP8GetCPUInfo pointer to the last used.
This is less code overall and each implementation is still
testable separately (by just changing VP8GetCPUInfo, but not
a separate threads!)

87c3d53180 method=0: Don't evaluate any predictor 
and apply Paeth predictor (predictor#11) for the low effort (m=0) mode.

For 1000 image PNG corpus (m=0), this change yields speedup of 25% at lower quality
range and about 10% for higher quality range.

24284459c7 replace unneeded calls to HistogramCopy() by swaps 
most of the time, we don't need to actually move the
data.

Compression is randomly slightly different, because HistogramCompactBins() changed.
Timing is about the same.

a3946b8956 enc_neon: fix building with non-Xcode clang (iOS) 
check for __apple_build_version__ to distinguish the two; a version
check could work as Apple bumped Xcode's to 5.x/6.x, but it's unclear
how upstream will deal with their versioning as they go 3.6+, so avoid
it for now.

Pascal Massimino
bad775715a simplify the Histogram struct, to only store max_value and last_nz 
we don't need to store the whole distribution in order to compute the alpha

Later, we can incorporate the max_value / last_non_zero bookkeeping
in SSE2 directly.
