Default user_friendly_filter feature submission

Attached is my submission for a feature update to the linux multipath. I
am trying to add a feature that allows dynamic user friendly names. I
feel this will make multipath, cluster friendly, in addition to making
multipath more malleable.
Right now the user has two dynamic options either use a wwid like
120030a80045bc60000007de800000293 that will be the same on all nodes of
a cluster or a name like mpathX where X might deviate on different nodes
of a cluster.
In practice the best practice is to static name all lun names in
/etc/multipath.conf on all nodes. On large clusters with small LUNS this
can easily run into thousands of lines per node.
I propose a feature that allows the user to supply a sed script that
will auto name the LUNS so for example...

user_friendly_names yes
120030a80045bc60000007de800000292 -> /dev/mpath/mpath0
120030a80045bc60000007de800000293 -> /dev/mpath/mpath1
while...
On a HP XP12000 class SAN the last 4 digits correspond to CU and LUN
user_friendly_names yes
user_friendly_filter "/bin/sed
s|^.{29}(.{2})(.{2})|lun_1_2|"

120030a80045bc60000007de800000292 -> /dev/mpath/lun_02_92
120030a80045bc60000007de800000293 -> /dev/mpath/lun_02_93

so for example with one line a Admin allows a DBA to see what lun
corresponds to what disk array.

Ex....
lun_01_01
lun_01_02
are all on one "parity group"
lun_02_01
lun_02_02
are on another.
If this patch is succesful I would considering working on a module
system so that every SAN has a unique naming scheme.

By default a XP12000 would automatically name its luns
XP_123_01_02
where 123 is a unique identifier for the san
while plugin in a EMC might give a name like
EMC_123_0001
But in any case the names will be the same on all nodes as long as the
filter is consistent.


Attached is a diff against redhat's source code
multipath-tools-0.4.7.rhel5.10 as that is the only code base I have
available for testing.


If a different format is needed please let me know.
