[PATCH] udev-007/extras/multipath update

[PATCH] udev-007/extras/multipath update

here is a clean-up patch :

* removes sg_err.[ch] deps
* makes sure the core code play nice with klibc
* port the sysfs calls to dlist helpers
* links against udev's sysfs (need libsysfs.a & dlist.a)
* finally define DM_TARGET as "multipath" as Joe posted the code today
  (not tested yet)
* push version forward (do you want it in sync with udev version?)

libdevmapper doesn't play well with klibc, so I wasn't able to produce a
static binary yet. Help needed here ... as I don't want to fall back to
merge libdevmapper code in the core.

It compiles here and doesn't segfault.
