231ec1fb6d Removing the indirection of meta-huffman tables. 
Now, the indexing refers directly to 5 huffman codes  that must be encoded separately.

* Refactor the incremental buffer-update code a lot.
* remove br_offset_ for VP8LDecoder along the way

19f6398ed7 add dec/vp8l{i.h,.c} from experimental 
Pulled from 5529a2e^.
The history of this and related files is a bit entangled so rather
trying to split the changes and introduce some noise in master's history
we'll start with a fresh snapshot.
The file progression is still available in the experimental branch.

7bb6a9ccd6 idec: fix internal state corruption 
A call to Append/Update would index the parts_ array w/-1 as num_parts_
had yet to be set by DecodePartition0. This would cause corruption
within the VP8Decoder member.

Fixes issue #106.

89cd1bb85b idec: fix WebPIUpdate failure 
If the first call to WebPIUpdate contained all of partition 0, but not
enough to decode a macroblock the test for max macro block size could
fail (4096 bytes) due to a memory buffer offset not being updated.
This change offsets the buffer in the same manner as Append().

Fixes issue #105.
