Export _lvm1_system_id as generate_lvm1_system_id and call it in
vg_setup() so it is set before writing the metadata to disk
and not missing from the initial metadata backup file.
Move the lvm1 sys ID into vg->lvm1_system_id and reenable the #if 0
LVM1 code. Still display the new-style system ID in the same
reporting field, though, as only one can be set.
Add a format feature flag FMT_SYSTEM_ON_PVS for LVM1 and disallow
access to LVM1 VGs if a new-style system ID has been set.
Treat the new vg->system_id as const.
As code uses strncpy(system_id, NAME_LEN) and doesn't set '\0'
Fix it by always allocating NAME_LEN + 1 buffer size and with zalloc
we always get '\0' as the last byte.
This bug may trigger some unexpected behavior of the string operation
code - depends on the pool allocator.
FIXME: refactor this code to alloc_vg.
Small refactor of main places in the code where a pv is added to a
vg into a small function which adds the pv to the list and updates
the vg counts.

Refactor adding to the vg->pvs list and incrementing the count, which
will allow further refactoring. Should be no functional change.

Clean up VG_RESIZEABLE flag by creating vg_is_resizeable().
Update comment - we no longer have ALLOW_RESIZEABLE.
Also use vg_is_exported() in one place missed by earlier patch.
Should be no functional change.
This patch is all just cleanup and no other patch depends on it.
Replace explicit dereference and check with vg_is_exported().
Update a few copyrights and remove unnecessary whitespace.
Should be no functional change.
link_lv_to_vg and unlink_lv_from_vg are the only functions
for adding/removing logical volume from volume group.
Only these function should manipulate with vg->lvs list.
Later patch initializes lv->vg after the LV structure is prepared,
so pass through cmd context and do not use vg->cmd here.
Also move LV id calculation (which uses lv->vg too).
Also properly free memory pool if operation fails.
The snapshot segment (snapshotX) is created twice
during the text metadata segment processing.
This can cause temporary violation of max_lv count.
Simplify the code, snapshot segment is properly initialized
in init_snapshot_seg function now and do not need to be replaced
by vg_add_snapshot call.
The vg_add_snapshot() is now usefull only for adding new
snapshot and it shares the same initialization function.
The snapshot name is always generated, name paramater can be
removed from function call.
Fix missing VG unlocks in some pvchange error paths.
Add some missing validation of VG names.
Rename validate_vg_name() to validate_new_vg_name().
Change orphan lock to VG_ORPHANS.
Change format1 to use ORPHAN as orphan VG name.
Fix some memory leaks in error paths found by coverity.
Use C99 struct initialisers.
Move DEFS into configure.h.
Clean-ups to remove miscellaneous compiler warnings.
