Dan Glastonbury 1b2a65cfc3 Bug 1281632 - P1: Extract creation parameters and pass via struct. r=gerald
Extract all the parameters passed to CreateAudioDecoder/CreateVideoDecoder and
place them into a structure that is passed down to the creation of the actual
decoder, where the relevant parameters can be extracted.

This makes it easier to add more arguments to the Create*Decoder calls in future.
