Change patch format to remove Git version
  * Patches 0001-0122 only have the patch format modified
Update to the head of the upstream staging branch plus redhat patches
  * Patches 0123-0134 & 1036-0142 are from the upstream staging branch
  * Patches 0143-1046 have been submitted upstream
  * Patch 0156 is a Red Hat only patch. Red Hat udev rules set ID_SERIAL
    from 60-persistent-storage.rules instead of 55-scsi-sg3_id.rules.
    Multipath's parse_vpd_pg83() function needs to match the ID_SERIAL
    value from udev.
Rename files
  * Previous patches 0123-0132 are now patches 1035 & 0147-0155
