Open for Beta1

Main things from rillian's todo are:
- implement non-vp3 qi matrix support in the reference decoder
- implement per-block qi switching as per the spec
- API updates. clean up api to add theora_ctl() for setting codec options, and move non-info-header data out of the theora_info struct into theora_state
4:2:2 and 4:4:4 pixel format support in the reference codec
<acolwell> the encoder/decoder inloop filter mismatch should probably be fixed before Beta 1 as well
- This is already done in alpha4.

this can wait for the next beta

add some sort of mmx(?) wims,VP3HoSwiYO or rodolphes sugestion?
- There is a branch of theora-lib with MMX optimization for encoding: theora-mmx.
- Also there is an experimental theora library supporting the whole spec and having also MMX optimization for decoding.

complete decoder?

Is beta1 supposed to ship with a decoder supporting the whole spec (comparison: Vorbis rc1/rc2)?
- Yes. See here.
