95dd5bc7fb configure: tune BUILD_DMEVENTD
Drop 'DMEVENT' make variable and use  BUILD_DMEVENTD like with other daemons.
NOTE: by default we do not build dmeventd - maybe time to change
as lot of build targets basically do need dmeventd...

Switch to use SYSTEMD_LIBS and avoid linking systemd library with
every linked tool when dbus notification are enabled.
(TODO  add missing testing for lib presence)

92b53a8077 configure: improve test for realtime clock
Check first if we need to even link -lrt  - since clock functions
are normally emebeded with recent  glibc (>=2.17)
Use standard  RT_LIBS name.
Avoid duplicate test for realtime clock with lvmlockd
Show better error message when realtime clock support is missing or
disabled.
Link  RT_LIBS explicitely with lvmlockd and lvmetad.

8256170e6a thin: warn about too big chunks size
lvm2 warned about zeroing and too big chunksize (>=512KiB), but
only during lvconvert, so lvcreate was creating thin-pools
without any warning about possible slowness of thin provisioning
because of zeroing.

5fd7c0aa33 dmsetup: Add concise table output format.
Create a new table output format that concisely shows multiple devices
on one line.

dmsetup table --concise [device...]

<dev_name>,<uuid>,<flags>[,<table>]*[;<dev_name>,<uuid>,<flags>[,<table>]*]*

Table lines are separated by commas.
Devices are separated by semi-colons.
Flags is currently 'ro' or 'rw' (and might be extended in a
yet-to-be-defined way in future).
Any comma, semi-colon or backslash within a field is quoted by a
preceding backslash.

The format can later be supplied as input to dmsetup or even to the
booting kernel as an alternative way to set up devices.

Based on patches submitted by
Enric Balletbo i Serra <enric.balletbo@collabora.com>.

f611b68f3c vgchange: separate change locktype and allow recovery
Add an independent command definition for "vgchange --locktype",
and split the implementation out of the set of common metadata
changes.  It is unlike normal metadata changes, and can only
be run by itself.  (Changing the lock type is similar in
principle to changing the VG name or the VG system ID; it
effects the ability of any host to see or access the VG.)

At some point this command lost the ability to forcibly change
the lock type of a shared VG to "none" (making it a local VG).
This can be necessary to repair shared VGs (e.g. recovery steps
that occur in vg_read are disabled for shared VGs because
they are not locked properly, or recovering sanlock locks
when the PV holding them is lost.)

"vgchange --locktype none --lockopt force VG" is used as the
method of forcing the shared VG to become local so that it
can be repaired.

c78316b7a5 raid: move syncing with udev into function
Since _deactivate_and_remove_lvs() is used in more then one place,
move the needed udev synchronization into this function so other
users automatically get correct fs state before next dm manipulation.

Assumption here is that this udev synchronization 'delay' may also
prevent to 'early' table reloads which might cause kernel problems
for md-core - but we may need more generic time-limited reload
frequency for raid devices.

Note: on udev-less system there will be almost no delay.

7b048f6b43 tests: aus.sh fix md teardown
Commit 8a912d6dbc missed the wrong logic,
we use 2 vars 'dev' & 'mddev' and their usage can't be mixed.

So correctly separate them so mddev keeps name of MD device.

9599645bb6 tests: aux.sh limit device
During test do a more close selection of visible devices.
If some test leaks a device with LVMTEST prefix, next
test should not be influnced (or parallel running one).

If the test is running in non-/dev  dir - it's already protected
by full path with $PREFIX in it - however it test is running
in real /dev dir - there was no such protection and test
were confused when they have seen such leaked device.
