13d05211d0 cleanup: dmeventd simplify status processing

6b701c3a48 cleanup: dmeventd abstract lvm2cmd interface
Keep  lvm2cmd  interface hidden inside dmeventd_lvm
and use regular 1/0 return codes, this we may
avoid using lvm2cmd.h in other lvm2 plugins.

b7741f0a83 libdaemon: header cleanup
Ensure  daemon-io.h is used as a generic header included
with configure defines before other headers.
(In future all lvm2 libraries should settle on a single lib.h header)
Rename couple defines to better match header file names.

e8a3ba1865 pvscan: Use lvmetad_used().
Config variables that are processed during setup prior to calling into
particular tools must not be accessed directly afterwards in case the
values already got overridden.

_process_config() already used the tests I'm removing here to call
lvmetad_set_active() and set up lvmetad_used().

702180b30c configure: use configure's --enable-udev-systemd-background-jobs by default
This should be the preferred way of configuring lvm2 for udev/systemd
since otherwise one can end up with the processes run from udev (the
pvscan we run for lvmetad update on events) to be killed prematurely
and this can end up with LVM volumes not activated in the end.

a6763c64a7 lvmdump: add -s to gather system info and context (currently systemd-related only)
This is sort of info we always ask people to retrieve when
inspecting problems in systemd environment so let's have this
as part of lvmdump directly.

The -s option does not need to be bound to systemd only. We could
add support for initscripts or any other system-wide/service tracking
info that can help us with debugging problems.

704609b17e profiles: comment out thin_pool_chunk_size in default.profile
By default, the thin_pool_chunk_size is automatically calculated.
When defined, it disables the automatic calculation. So to be more
precise here, we should comment it out for the default.profile.

Also, "lvm dumpconfig --type profilable" was used here to generate
the default.profile content. This will be done automatically in the
future once we have the infrastructure for this in (see also
https://bugzilla.redhat.com/show_bug.cgi?id=1073415).

8980592514 alloc: Correct existing use of positional fill.

first with then without positional fill.

allocation when number of stripes varies as reported here:

1bf4c3a1fa alloc: Introduce A_POSITIONAL_FILL.

positionally (with a slot corresponding to each 'leg') rather
than sequentially (with all suitable areas found, to be sorted
and selected from).

92ee51a4c3 tests: check there is really pvmove lv
Since the kill may take various amount of time,
(especially when running with valgrind)
check it's really pvmoved LV.

Restore initial restart of clvmd - it's currently
broken at various moments - basically killed lvm2
command may leave clvmd and confusing state leading
to reports of internal errors.

7075656034 clvmd: drop reply_mutex
Added complexity with extra reply mutex is not worth the troubles.
The only place which may slightly benefit from this mutex is timeout
and since this is rather error case - let's convert it to
localsock.mutex and keep it simple.

cc0096ebdd clvmd: move mutex init and detroy
Move the pthread mutex and condition creation and destroy
to correct place right after client memory is allocatedd
or is going to be released.

In the original place it's been in race with lvm thread
which could have still unlock mutex while it's been already
destroyed.

91f4e09b48 clvmd: fix test mode race
When TEST_MODE flag is passed around the cluster,
it's been use in thread unprotected way, so it may have
influenced behaviour of other running parallel lvm commands
(activation/deactivation/suspend/resume).

Fix it by set/query function only under lvm mutex.
For hold_un/lock function calls check lock_flags bits directly.

84ff3ae703 pvmove: remove locked flag from error pvmove0
When pvmove0 is finished, it replaces temporarily pvmove0
with error segment, however in this case, pvmove0 remains
unremovable in case pvmove --abort is interrupted in this
moment - since it's not a pvmove anymore and normal
lvremove can't be used to remove LOCKED lv.
