Original commit message from CVS:
* docs/gst/gstreamer-docs.sgml:  I got tired of the reference
manual being such complete crap, that I decided to do major
hacking of it.  This checkin replaces any fine tuning that
may have been done previously, with the benefit of actually
being complete for much of the API that was changed since
0.6.  Further fine tuning will occur shortly.  (bug #134721)

<!-- ##### SECTION Title ##### -->
GstData
<!-- ##### SECTION Short_Description ##### -->
Abstract structure for information that is passed among elements
<!-- ##### SECTION Long_Description ##### -->
<para>
This abstract structure provides a common base for #GstBuffer, #GstBufferPool
and #GstEvent. It is the main data type that is passed along in a pipeline.
GstData provides refcounting, freeing and copying for its child classes.
