bdadde2f7a Use -d to control level of messages sent to syslog by dmeventd.
Change -d to -f to run dmeventd in foreground.

e73debb2db Use Require.private: field for devmapper-event.pc
Move devmapper to Require.private: field and remove unneeded libs
from Libs.private: as they are dependencies of devmapper library.

75b55f1136 Plugins do not use pthread or lvm2cmd directly.
Plugins are using pthread and lvm2cmd libraries indirectly
through devmapper-event-lvm2, so link only with libraries used by them.

180b3dea11 Install plugins to subdirs
Target install_dm_plugin installs files to libdir/device-mapper.
Target install_lvm2_plugin installs files to libdir/lvm2.

Both targets creates relative links to libdir to keep the code
compatible with current dlopen handling.

Once we will be able to read plugins from subdir, links
could be removed.

bda3982016 Use UUIDs instead of names while processing event handlers.
Internally, we used DM names instead of UUIDs while processing event
handlers. This caused problems while trying to vgrename a VG with active LVs
where the names are being changed and so the devices were not found then.
The patch also contains a little bit of refactoring, moving "build_dlid" code
found in dev_manager.c to "build_dm_uuid", now in lvm-string.c (so we have
build_dm_uuid and build_dm_name at one place).

23b059e7b7 INSTALL rules updates
Patch is inspired by Debian's extra patch.

- removes OWNER & GROUP make vars they are parts of INSTALL command.
- adds INSTALL_PROGRAM for executable, uses $(INSTALL)
- adds INSTALL_DATA for non-executable data, uses ($INSTALL)
- adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL)
- adds configure option --enable-write_install - to support
  installatin of writable files used by distribution
- replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX)
- installs .a files from static builds without executable flag
- installs .a files to $(usrlibdir) instead of $(libdir)
- installs all static binaries to $(staticdir)
- create .so links for devel package in $(usrlibdir) instead of
  $(libdir)
- makes .so and .so.LIB_VERSION files within builddir
- removes VERSIONED_SHLIB and created versioned LIB_SHARED automagicaly
- install LIB_SHARED via install_lib_shared target
- install plugins via install_lib_shared_plugin target
- prints whole 'install' command during installation instead of less
  informative "Installing  $(something) $(somewhere)"
- install multiple man pages with one INSTALL command
- use DISTCLEAN_TARGETS instead of creating multiple distclean targets

c737d34804 Use vpath instead of VPATH.
Usage of VPATH makes troubles when used within $(builddir).
Not only source files are being found through VPATH,
but targets as well. (make --debug=v)

Thus if user builds the code in $(srcdir) and also in some $(builddir)
he gets mangled results as some generated files (i.e. .export.sym)
are 'reused' from $(srcdir) instead of $(builddir).

This patch switches to use vpath were we could explicitly name
suffixes that should be looked via vpath - we must take care,
we do not generate files with these suffixes:
.c, .in, .po, .exported_symbols

71cb54406a Don't kill the parent if debugging.
If dmeventd runs with -d flag, it doesn't fork into backgroud.
The command kill(getppid(), SIGTERM) attempts to kill the parent dmeventd
process, however, if there is no parent, it kills whatever process spawned
dmeventd. In case of debugging with gdb, the parent is gdb, thus
kill(getppid(), SIGTERM) kills the debugger.

dee5782e76 Remove mlockall() form dmeventd
As the header file <sys/mman.h> was not included in dmeventd.c
thus missed definition of MCL_CURRENT so this patch only makes
it obvious we were not locking memory here.

This patch has no functional change.
Later part of this patch set handles mlockall() via memlock_inc_daemon().

b41f5924bf Update cflow file generation - support build dir and use $(top_srcdir)
to obtain sources. Create make.tmpl target for
simplier generation of cflow files with the help of
CFLOW_LIST, CFLOW_LIST_TARGET, CFLOW_TARGET.
Still cflow usage is not perfect.

7a369d3704 Add ability to create mirrored logs for mirror LVs.
This check-in enables the 'mirrored' log type.  It can be specified
by using the '--mirrorlog' option as follows:
#> lvcreate -m1 --mirrorlog mirrored -L 5G -n lv vg

I've also included a couple updates to the testsuite.  These updates
include tests for the new log type, and some fixes to some of the
*lvconvert* tests.

f8f6ec92b1 This patch add SELINUX_LIBS and STATIC_LIBS variables.
For static builds dependency for SELinux libs is not handled by 'ar'.
Till better solution is found, for static builds STATIC_LIBS is used.

Patch updates SELinux detection to use 3rd & 4th parameter for Success/Fail.
Also removes detection of pthread from this check as we know which
version of libdevmapper we are going to link with lvm after merge.

SELinux header check moved to the SELinux test code.

bf8c8a6d61 Remove empty "repaired" devices if empty in lvconvert.
The logic was that lvconvert repair volumes, marking
PV as MISSING and following vgreduce --removemissing
removes these missing devices.

Previously dmeventd mirror DSO removed all LV and PV
from VG by simply relying on
vgreduce --removemissing --force.

Now, there are two subsequent calls:
lvconvert --repair --use-policies
vgreduce --removemissing

So the VG is locked twice, opening space for all races
between other running lvm processes. If the PV reappears
with old metadata on it (so the winner performs autorepair,
if locking VG for update) the situation is even worse.


Patch simply adds removemissing PV functionality into
lvconcert BUT ONLY if running with --repair and --use-policies
and removing only these empty missing PVs which are
involved in repair.
(This combination is expected to run only from dmeventd.)
