Subject: [PATCH 4/6] gluster: default scheme to gluster:// and host to localhost.

O-Subject: [PATCH qemu-kvm-rhev RHEL7.1] gluster: default scheme to gluster:// and host to localhost.

From: Paolo Bonzini <pbonzini@redhat.com>

Currently, "gluster:///volname/img" and (using file. options)
"file.driver=gluster,file.filename=foo" will segfault.  Also,
"//host/volname/img" will be rejected, but it is a valid URL
that should be accepted just fine with "file.driver=gluster".
Accept all of these, by inferring missing transport and host
as TCP and localhost respectively.
