[Xen-tools] [PATCH 1/2] Interface cleanup and renaming

[Dan Smith <danms@xxxxxxxxxx>]

The attached patch renames several xm commands per the recent
discussion on xen-tools.  It makes nothing worse, and does fix another
IndexException in block-create (now block-attach).  The network-attach
and network-detach stubs are also included, but not yet listed in the
help output.
