Incremental decoding: internal context corruption.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a new incremental decoder, WebPINewDecoder(NULL);
2. Call WebPI(Update|Append)

What is the expected output? What do you see instead?
The first and any subsequent calls to (2) prior to decoding partition 0 will 
cause a negative -1 index to be used into an array contained within the 
VP8Decoder member.

Please use labels and text to provide additional information. Since 
fc7815d (and therefore v0.1.3) this would be a value within thread_ctx_ 
(currently io->a on Linux gcc-x86_64). Prior versions including v0.1.2 would be 
elsewhere, the effects of this are untested.
