Allow xendomains script to work with xl list -l

This patch inserts a line feed after each comma in the output from
xl list -l, allows there not to be a space between "name" and "domid" keys
and their value, and accepts the "Xen saved domain" value as a valid header
for a saved xen image if xl is being used.
