o the _status fxns now take more arguments - this way i don't get the
...
preparsed status info, shove it all into a string, and then parse it
again to get the info back out (which is what i was doing before)
o basically that's it...i like this *much* better than the previous
method and i think it makes the _status fxn more flexible if we need
to use it to get other info out.

o Not sure if the code in dev_manager is really optimal, but it works..
will look at adjusting it a bit now.
o I *think* it works right when one snapshot if full but others aren't,
but I haven't really been able to test it because the full snapshot
somehow resets itself and weird things start happening to the system...

Merge with text format branch.
...
Lots of changes/very little testing so far => there'll be bugs!
Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files. Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.
Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).
e.g. metadata {
dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}
Plenty of refinements still in the pipeline.
