dixie: initial interface

The "dixie" project will be a rewrite of much of the VP8 decoder core.
Some of the goals are:

* Increase speed by paying more attention to data locality and
cache layout, and by eliminating redundant work in general.

* A different approach to multithreading, to treat all threads as
equal and working on larger work units than a single MB.

* Expose more of the bitstream to the application, essentially
creating a vp8 parser utility. This could be useful for analyzing
the complexity of a stream, to help set conformance points.

* If the above goals are met successfully, replace the reference
decoder.

For those interested in the etymology of the term "dixie:"
decoder2 -> dx2 -> dxii -> dixie
