74356eb558 Add a simple cleanup step in mux assembly:
In particular, this removes any unnecessary FRGM/ANMF/ANIM chunks, and
indirectly leads to removal of unnecessary VP8X chunks as well.
This is especially useful for GIF to WebP conversion - it saves 56 bytes
(ANMF: 16+8 bytes, ANIM: 6+8 bytes, VP8X: 10+8 bytes) for non-animated GIFs.

fa30c86323 Update mux code to match the spec wrt animation
- Allow a duration of 0
- Rename LOOP chunk to ANIM and add the background color field to it.
- Add a disposal method field for each animation frame.
- Modify webpmux.c binary interface to allow the input of background color
  and disposal methods. Also make '-loop' and '-bgcolor' arguments optional
  with some default values.

d9c5fbefa4 by-pass Analysis pass in case segments=1
10-15% faster encoding.

Almost same output, binary wise. The main difference is
that we can't compute uv_alpha susceptibility, means there
can be subtle differences with different -sns values.

a00a3daf5b Use 'frgm' instead of 'tile' in webpmux parameters
- Also, use the term 'fragments' instead of 'tiling' in code
- This makes code consistent with the spec.

81b8a741ed Design change in ANMF and FRGM chunks:
- Make ANMF and FRGM chunks hierarchical so that they encompass all chunks of
  that frame.
- Use this in demuxer: stop parsing a frame if all image data for it isn't
  available yet. Thus, we have a frame-level incremental support; that is,
  all frames that are fully available can be parsed.
- Note: We still keep incremental support for single images - so that they can
  be decoded with incremental decoding.
