ba68aed836 scripts: activation generator: do not use --sysinit if lvmpolld used
If lvmetad is not used, we generate lvm2-activation{-early,-net}.service
systemd services to activate any VGs found on the system. So far we used
--sysinit during this activation as polling was still forked off of the
lvm activation command.

This has changed with lvmpolld - we have proper lvmpolld systemd
service now (activated via its socket unit). As such, we don't need
to use --sysinit anymore during activation in systemd environment
as polling was the only barrier to remove the need for --sysinit.

01b06cb71b polldaemon.c: modify log levels in report_progress
There's a race when asking lvmpolld about progress_status and
actually reading the progress info from kernel:

Even with lvmpolld being used we read status info from
LVM2 command issued by a user (client side from lvmpolld perspective).
The whole cycle may look like following:

1) set up an operation that requires polling (i.e. pvmove /dev/sda)
2) notify lvmpolld about such operation (lvmpolld_poll_init())
3) in case 1) was not called with --background it would continue with:
4) Ask lvmpolld about progress status. it may respond with one of:
   a) in_progress
   b) not_found
   c) finished
   d) any low level error

5) provided the answer was 4a) try to read progress info from polling LV
(i.e. vg00/pvmove1). Repeat steps 4) and 5) until the answer is != 4a).

And now we got into racy configuration: lvmpolld answered with in_progress
but it may be the that in_between 4) and 5) the operation has already
finished and polling LV is already gone or there's nothing to ask for.
Up to now, 5) would report warning and it could print such warning many
times if --interval was set to 0.

We don't want to scary users by warnings in such situation so let's just
print these messages in verbose mode. Error messages due to error while
reading kernel status info (on existing, active and locked LV) remained
the same.

f3c7bd4004 makefiles: use bash subshell
Avoid using  make's $(shell invocation since the eval order is
then somewhat different and use $$(  subshell.

This also fixes a problem when more then one symbol is found,
since target shell has been given separate word list
so the 'R' assignment would need "" around it.

e6b5eb88f2 polldaemon.c: do not report error when LV not found
currently in wait_for_single_lv() fn trying to poll missing pvmove LV
is considered success. It may have been already finished by another
instance of polldaemon. either by another forked off polldaemon
or by lvmpolld.

Let's try to handle the mirror conversion and snapshot merge the same
way.

7a8ce8dbf7 polldaemon: remove get_copy_vg and get_copy_lv wrappers
These wrappers have been replaced by direct calls
to vg_read() and find_lv() in previous commits.

This commit should have no functional impact since
all bits were already unreachable.

e5e0e22022 polldaemon: move dev_close_all out of poll_get_copy_vg
let's call dev_close_all() only before we're about to 'sleep'
for at least one second during the polling.

(it's questionable whether to call dev_close_all() at all in
polldaemon code. Natural extension would be to drop it completely)

dc49e1cde0 configure: update localedir
Previous patch incorrectly skipped replace of @LOCALEDIR@.

The standard option is --localedir  so use --with-localedir
as backward compatible option and set localedir if it's not
yet been set (if the could ever happen).

Use double-eval to translate $datarootdir to $prefix to real dir.

76cc477fba tests: no warn if test does not need thin_repair
Set LVM_TEST_THIN_REPAIR_CMD to /bin/false for test which
doesn't need it.

This way - even if on the system there is no such tool present,
test will not result with warning about missing tool.

Also remove from Makefile settings of TEST vars which are set in
through /lib/paths  - this also allows to override them in test.

b91e1ea95e lvmpolld: introduce client functionality
as of now lvmpolld works as client utility for
querying running instance of lvmpolld server
on metadata, state, etc.

Currently the only request implemented is the '--dump'.
It prints out full lvmpolld state (mimics lvmdump -p command).
