vorbisdec: support modern Tremor versions

Browse source 
Tremor changed to use standard libogg rather than its own incompatible
copy back in Aug 2010 (r17375), causing gst-plugin-base build to fail.

Tremolo so far unfortunately hasn't been updated. Restructure
vorbisdeclib.h so the int/float logic is seperate from the ogg handling,
and only use the legacy _ogg_packet_wrapper code for Tremolo.
