tools/gst-xmlinspect.c: De-cruft a bit. If no argument is specified, print all elements in

Browse source 
Original commit message from CVS:
* tools/gst-xmlinspect.c: (print_element_info), (main):
De-cruft a bit. If no argument is specified, print all elements in
XML syntax rather than a freestyle list of elements like gst-inspect.
Also, don't print XML header chunk unless we actually have something
to print (ie. don't print it before an error message); print error
message to stderr not stdout. Remove support for printing plugin
info (it would just output something freestyle along the lines of
gst-inspect so far), which fixes #514507. Also add license header.
