2937b51eaa Fallback to full rescan for missing device
Fix bug when NULL could have been passsed as 'data'
to _add_pv_to_list() if 'dev' is NULL.

Now it fallbacks to complete scan.

4059d2219c Recognise DRBD device part and handle it similar to MD devices.
The DRBD uses underlying device so code should prefer top
device if duplicate is found.

Patch also introduce
        dev_subsystem_part_major and dev_subsytem_name
functions to easily handle all these replication susbystems
and not hardcode md_major call.

See https://bugzilla.redhat.com/show_bug.cgi?id=530881
for full problem description.

introducing too many new bugs:-)  (Same exercise required for other archs.)

25b733809a 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.

15c325f06a o Use new LCK_HOLD flag to indicate whether lock should be held on return
from lock_vol() - otherwise it now attempts to acquire the lock and then
  immediately releases it.
o Extend the id field in struct logical_volume to hold VG uuid + LV uuid
  for format1. This unique lvid can be used directly when calling lock_vol().
o Add the VG uuid to vgcache to make VG uuid lookups possible.  (Another
  step towards using them instead of VG names internally.)
