i) Added a little macro to aid defining the status flags.

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.

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.

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.

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.)

o Use 'pvcreate --setphysicalvolumesize' with no short form (instead of -s)
...
and add severe warning if it's used to make a device seem bigger than
it really is. This is not an option people should be using as it
breaks metadata integrity.
o Use uint64_t throughout (rather than unsigned long long)
o Convert a few messages that contain pathnames into the more common form:
pathname: message
