097d49e73d i) There's now a seperate field in struct logical_volume that stores the 
allocation policy.  This can currently take one of three values:

   typedef enum {
        ALLOC_NEXT_FREE,
        ALLOC_STRICT,
        ALLOC_CONTIGUOUS
   } alloc_policy_t;

    Notice that 'SIMPLE' has turned into the slightly more meaningful NEXT_FREE.

ii) Put code into display.[hc] for converting one of these enums to a
    text representation and back again.

ii) Updated the text format so this also has the alloc_policy field.

fccc39a3a7 o Added function find_snapshots to snapshot_manip.c that returns a list 
of snapshots whose origin is the lv passed in.
 o Used this new function to make lvdisplay properly display all snapshots
   attached to a origin.

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.)

413cc9189e Begin conversion so LV id is passed to activation unit instead of 
struct logical_volume.
