this is more a workaround than a fix. this change forces the tables
from yuv.h into the data section rather than generating them as common
blocks. prior to this the linkage would fail with e.g.,
Undefined symbols:
...
"_VP8kClip4Bits", referenced from:
_Yuv444ToRgba4444 in libwebp.a(libwebpdsp_la-upsampling.o)
broken since:
48f8275 add colorspace for premultiplied alpha

- Add details about the VP8L chunk support.
- Also add new example bitsteams containing VP8L chunk.
- Add back a section describing the VP8 chunk.
- Restrict some fields to 16 or 24 bits instead of 32 bits.
- Fields whose values are always positive are stored 1-based
instead of 0-based.
- Unknown chunks can only occur at certain places in the file.
- Remove the restriction for some fields to be divisible by 32 or 16.
Instead they are restricted to be even.
- Add a restriction for (canvas_width * canvas_height) product.
- Add 3 bits for rotation & symmetry in VP8X flags.
- Add some new example layouts.
- Add/clarify some nitty-gritties throughout the doc.
- Use the terms frame/tile more consistently and logically.
- Update related TODOs.

* add a real proper pointer for holding memory chunk pointer
(instead of using y and argb fields)
* polish the doc with details
* add a WebPPictureView() that extract a view from a picture
without any copy (kind of a fast-crop).
* properly snap the top-left corner for Crop/View. Previously,
the luma position was not snapped, and was off compared to the chroma.

Example kramdown command line to apply syntax highlighting requires
kramdown latest. Command is slightly different for earlier versions.

'Set' and 'Get' methods for images take/return a bitstream as input,
instead of separate 'image' and 'alpha' arguments.
Also,
- Make WebPDataCopy() a public API
- Use WebPData for storing data in WebPChunk.
- Fix a potential memleak.

Substantial edit, though less than 100% thorough. This
makes changes that are clearly safe, but avoids others
where my domain knowledge is incomplete and accuracy
might be compromised.

Check for valid bounds on the 'dist' in backward reference case.
Clamp it to 1 in case of zero and negative values.

Adds a test of enc->mb_h_ to VP8IteratorProgress() to avoid a division
by zero. Fixes issue #121.
