Changed the GstPadFactory and added the GstPadTemplate.

Browse source 
Original commit message from CVS:
Changed the GstPadFactory and added the GstPadTemplate.

The GstPadFactory is an easy way to define a pad with capabilities.
The GstPadFactory is converted into a GstPadTemplate. The template is
used to create new pads and to expose the possible pads used in an
element to the plugin system.

updated mp3parse, mpg123, cdparanoia to the new API.
Rerun gstreamer-register because the XML definition has changed.
