Replace explicit strcmps with obd_uuid_equals.

Replace explicit strcmps with obd_uuid_equals.

Replace (most) literal "OBD_CLASS_UUID" string use with a shared lctl_fake_uuid
structure.

Fix leak of reqmsg for delayed replies that are aborted (such as when recovery
times out after some clients have completed their replay).

b=1300: When we drop a reply due to obd_fail_loc, wait for ack-or-commit.
        Also, find locks for resent lock enqueues without use of
        exp_outstanding reply, which may well be long gone.

Send the right handle for reconnect (not the portals_handle, which has h_link
where we want to find a cookie, etc.).

Don't allocate transnos for requests that already have them (read: requests that
are being replayed).
