Since LVM 2.02 it appears that compiling LVM on a platform which
lacks a shared library linker/loader will fail to produce any
binaries (dmsetup, lvm2, etc).
Adds support for the standard --disable-shared flag, and
use it to disable attempts at building shared libraries.

Fix some interactions between device IDs and hints. Hints
may limit the scanned devices which should not always trigger
a search for the PVs that were intentionally not scanned.
Hints should also be invalidated if they contain a device
that's become excluded by an internal filter such as the
device_id filter.
Fix commit 847f1dd99c
"device_id: rewrite validation of devname entries"
which began calling device_ids_refresh() in cases where it
was unnecessary, leading to extra PV searches and warnings.
Specifically, a command like "lvs <vg>" would use the hints
file to scan only devices for the named VG. This means that
scanning other PVs would be skipped, and device IDs of those
PVs could not be validated because there are no PVID values
to verify. This missing info would cause messages about
the missing info, and would cause device_ids_refresh to
search for the PVs that had been intentionally skipped.
If the system changes, locate PVs that appear on different devices,
and update the device IDs in the devices file. A system change is
detected by saving the DMI product_uuid or hostname in the devices
file, and comparing it to the current system value. If a root PV
is restored or copied to a new system with different devices, then
the product_uuid or hostname should change, and trigger lvm to
locate PVIDs from system.devices on new devices.
Make a local copy of the 'idx' string to avoid
overlapping during the rebuild of name.
This fixes cases where users specified raid
component LVs for moving.

When creating thin pool or check pool there is allocated LV
for metadata and for such allocation user should be able to
specify list of PVs on cmdline.
Also fix unused passed list of PV for thick to thin conversion,
where the code was using whole PV set from a VG (but since it's
been not enabled on cmdline, user could not hit this issue).
Also remove unneeded initialization of use_pvh.
Reuse existing report/headings config setting to make it possible to
change the type of headings to display:
0 - no headings
1 - column name abbreviations (default and original functionality)
2 - full column names (column names are equal to exact names that
-o|--options also accepts to set report output)
Also, add '--headings none|abbrev|full|0|1|2' command line option
so we are able to select the heading type for each LVM reporting
command directly.
Set the lock_args string in addition to doing initialization.
lvconvert calls lockd_init_lv_args() directly, skipping
the normal lockd_init_lv() which usually sets lock_args.
lvmlockd locking for swapmetadata adjusted for commit
ac36153e99 lvconvert: preserve UUID for swapped metadata
Now that the LV uuid is swapped between LVs, the lvmlockd lock can
simply be moved between them, and the same lock can continue to be
used for the LV outside of the pool.
Once lvm2 repairs pool's metadata LV and preserves the original metadata LV
with unmodified metadata, for such LV in VG use newly created UUID for new
_pmspare and actually preserve UUID for this hidden _pmspare (if it
exists).
The lockd lock needs to be freed for the LV that is becoming
the new metadata LV, and a new lockd lock needs to be created
for the old metadata LV that is becoming an independent LV.
Fixes b3e45219c2
Use cachepool name for create name for metadata backup LV.
(so we do not generate 2 'sequences' of metadata filenames.)
Move path preparion before handling _pmspare.
Also drop extra call to sync_local_dev_names() as it's
already got in sync with call of exec_cmd().
When repair thinpool or cachepool, lvm2 leaves original metadata
volume backup. To avoid potential damage of those data, mark such
volume as 'read-only' and also allow user to use --setactivationskip
option for this volume.
TODO: likely better default would be to automatically skip, but
that might need some more thinking about recovery reporting doc.
Replace the use of internal /dev/mapper names with the use of
public LV names /dev/vg/lv for use with repair tools.
For this make the activation of _pmspare LV to be handled as
a component activation with public name.
Metadata is already atomatically activated this way (as readonly).
So if there is any 'error' happening, we leave public LVs in
system.
lvresize --usepolicy requires resized LVs to be active.
(So it's not only required for shared VG).
The test for active pool needs to use lv_info to query 'layer'
otherwise the pool is considered inactive if it was not activated
explicitely - thun 'implicit' activation with VDO or ThinLV was
not managed by --usepolicy option.
