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.

Remove the _ in front of the endianness prefix.
Remove the _3 postfix for the 24 bits formats.
Add a _32 postfix after the formats that occupy extra space beyond their
natural size.
The result is that the GST_AUDIO_NE() macro can simply append the endianness
after all formats and that we only specify a different sample width when it is
different from the natural size of the sample. This makes things more consistent
and follows the pulseaudio conventions instead of the alsa ones.
Rework the audio caps similar to the video caps. Remove
width/depth/endianness/signed fields and replace with a simple string
format and media type audio/x-raw.
Create a GstAudioInfo and some helper methods to parse caps.
Remove duplicate code from the ringbuffer and replace with audio info.
Use AudioInfo in the base audio filter class.
Port elements to new API.
