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).

Add --dataalignment to pvcreate to specify alignment of data area. (mbroz)
...
This patch is not fully tested and leaves some related bugs unfixed.
Intended behaviour of the code now:
pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.
In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.
Currently, the field storing the size of the data area in the PV label
header always holds 0. As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).

Rename get_vgs() to get_vgnames() and clarify related error messages.
...
get_vgs() really returns a list of vgnames. In the future we will use
get_vgs() to return a list of vg structures, similar to get_pvs().
