Collapse the Ogg demuxer, and the Theora, Vorbis and Speex decoders in the same 'xiph' plugin.
As the three decoders requires Ogg support, and requires an Ogg demuxer to play, enabling any one of them will then enable the ogg demuxer.
The Ogg demuxer, on its own, needs to know which of the three formats are enabled, or it will not be able to properly decode them.
With this change, only one plugin will need to load and know about Xiph formats and libraries.
