Clean up the virsh man page description for --pool-create-as in order
to better describe how the various arguments are used when creating
(or defining) a logical pool.

Also move the --print-xml to the end of the qualifiers since it's not
properly positionally situated for both --pool-create-as and --pool-define-as.

Finally modify the storage pool XML parsing algorithm to check for the
mismatched "name" and "source-name" as well as a more general if not
provided, then set the default source format.
