If some lvm1 device is missing, lvm fails on all operations
# vgcfgbackup -f bck -P vg_test
Partial mode. Incomplete volume groups will be activated read-only.
3 PV(s) found for VG vg_test: expected 4
PV segment VG free_count mismatch: 152599 != 228909
PV segment VG extent_count mismatch: 152600 != 228910
Internal error: PV segments corrupted in vg_test.
Volume group "vg_test" not found
Allow loading of lvm1 partial VG by allocating "new" missing PV,
which covers lost space. Also this fake mising PV inform code
that it is partial VG.

Pass metadataignore through PV creation / setup paths.
As a result of this cleanup, we can remove the unnecessary setting
of mda_ignore bits inside pvcreate_single(), after call to pv_create.
For now, just set metadataignore to '0' in some places. This is
equivalent to the prior functionality, although the 0 is given
by the caller not hardcoded in _mda_setup() call.

Add a second mda list, metadata_areas_ignored to fid, and a couple
functions, fid_add_mda() and fid_add_mdas() to help manage the lists.
These functions are needed to properly count the ignored mdas and
manage the lists attached to the 'fid' and ultimately the 'vg'.
Ensure metadata_areas_ignored is initialized in other formats, even
if the list is never used.

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

Adds pe_align_offset to 'struct physical_volume'; is initialized with
set_pe_align_offset(). After pe_start is established pe_align_offset is
added to it.

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.

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).
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).
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.
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-) (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug
