Pass them along to internal 'pic' object, so that progress can be reported back
and user data can also be inspected.

We now get error string instead of printing it.
The verbose option is now only used to print info and warnings.

It was needed earlier for WebPAnimEncoder API when it was using structs
like WebPConfig, but it only uses pointers to those now.

Earlier, we stored a 1x1 frame for such frames. Now, we drop every such
frame and increase the duration of its previous frame instead.
Also, modify the anim_diff tool to handle animated images that are
equivalent, but have different number of frames.

When converting from video sources, the duration of current frame
is often unavailable until the next frame. So, we internally convert
timestamps to durations.

Some frames that were previously selected as key-frames were incorrectly
being reset to sub-frames.

SanitizeEncoderOptions() was changing kmin to 2 too, which resulted in a
bad state with kmin == kmax.

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.

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.

Given that we decided to only handle frame disposal for output WebP
internally,
only current and previous canvas need to be maintained.

A separate API to generate animated WebP images.
It will eventually replace the internal gif2webp_util methods.
Also: update makefiles.
