[PATCH] update extras/multipath

incremental to udev-016/extras/multipath,

* don't rely on the linux symlink in the udev/klibc dir since
  udev build doesn't use it anymore. This corrects build breakage
* remove make_dm_node fn & call. Rely on udev for this.

The first patch is to be applied.
The second is conditioned by udev dealing correctly with devmap names.

For this I can suggest a CALLOUT rule like this :
KERNEL=3D"dm-[0-9]*", PROGRAM=3D"/tmp/name_devmap %M %m", NAME=3D"%k", SY=
MLINK=3D"%c"

With name_devmap like :
#!/bin/sh
/usr/sbin/dmsetup ls|/bin/grep "$1, $2"|/usr/bin/awk '{print $1}'
