1bd72d90a4 Add vg_reduce to metadata.c and metadata-exported.h
This function behaves a little bit different than vg_reduce_single, because
it allowes to remove even the latest pv. This has been done to be consistent
to lvm_vg_create, which creates an empty vg.

removed_pvs has been added to the volume_group struct. vg_reduce adds remove
pvs to this list to be able to commit the changes for the pvs in lvm_vg_comm
in liblvm2app.

Initialize removed_pvs list in format-specific volume_group constructors.
Ideally, we should have a base constructor here that initializes the general
non-format specific members of struct volume_group.  But until then, there
are multiple places to initialize these members.  Maybe a better patch would
be a base constructor patch for struct volume_group.  That is more work
though.

0b706ac672 Introduce link_lv_to_vg and unlink_lv_from_vg functions.
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.

d60f341d96 Remove vg->lv_count and use counter function.
This should not cause problems but simplifies code a lot.

(the volumes_count is merged and renamed with lvs_visible
function by following patch.)

4b13d5a823 Fix snapshot segment import to not use duplicate segments & replace.
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.

8e1d5615b4 Introduce memory pool per volume group.
Since now, all code reading volume group is responsible for releasing
the memory allocated by calling vg_release(vg).
(For simplicity of use, vg_releae can be called for vg == NULL,
the same logic like free(NULL)).

Also providing simple macro for unlocking & releasing in one step,
tools usualy uses this approach.

The global memory pool (cmd->mem) should be used only for global
physical volume operations.

This patch have to be applied with all subsequent patches to complete
memory pool per vg logic.

Using separate memory pool has quite bit memory saving impact when
using large VGs, this is mainly needed when we have to use
preallocated and locked memory (and should not overflow from that
memory space).

bc437feded Add "flags" metadata field (akin to "status") for backward-compatible flags.
The "status" field is treated as it ever has been, unknown flags there are
treated as fatal metadata errors. However, in the "flags" field, any unknown
flags will be ignored and silently dropped. This improves
backward-compatibility possibilities. (Any versions without support for this
new "flag" field will drop the field altogether, which is same as ignoring all
the flags there.)
