6f4d25ec7f Fix clvmd startup bug introduced in cman/gulm amalgamation. bz#145729
Improve reporting of node-specific locking errors so you'll get
somthing a little more helpfiul than "host is down" - it will now tell
you /which/ host it thinks is down.

8ef2b021ed Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

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.

568d7229bf Review locking: block signals instead of ignoring them and restore state
afterwards; avoid race condition with unlink; add LCK_HOLD to process_each_vg.

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.)

f4cbeaf0ac o Lock mechanism for LV activation
o #defines for common lock flag combinations
o Try out hyphens instead of colons in device-mapper names - does this
  make messages containing filenames easier to read?

03888774a5 o Added functions to display what's in the archive.
o  For now vgcfgrestore -l <vg> displays this list.

A bit hacky, but it'll get better.
