This commit splits the Tremor fixed-point implementation
out of the libvorbis package and creates a new package
called 'tremor' for it.

+	  Tremor is a fixed point implementation of an Ogg Vorbis
+          decoder. It provides a decoding API similar to libvorbis,
+          but gives much better performance on systems without a
+          floating-point unit.
