9a96f930a7 configure: run directory configuration cleanup
There were several hard-coded values for run directory around the code.
Also, some tools are DM specific only, others are LVM specific and there
was no distinction made here before. With this patch applied, we have
this cleaned up a bit (subsystem in brackets, defaults in parentheses):

          [common] configurable PID_DIR     (/var/run)

 lvm      [lvm]    configurable RUN_DIR     (/var/run/lvm)
                   configurable locking dir (/var/lock/lvm)

 clvmd    [lvm]    configurable pid file    (PID_DIR/clvmd.pid)
                   socket                   (RUN_DIR/clvmd.sock)

 lvmetad  [lvm]    configurable pid file    (PID_DIR/lvmetad.pid)
                   socket                   (RUN_DIR/lvmetad.socket)

 dm       [dm]     configurable DM_RUN_DIR  (/var/run)

 cmirrord [dm]     configurable pid file    (PID_DIR/cmirrord.pid)

 dmeventd [dm]     configurable pid file    (PID_DIR/dmeventd.pid)
                   server fifo              (DM_RUN_DIR/dmeventd-server)
                   client fifo              (DM_RUN_DIR/dmeventd-client)

The changes briefly:
  - added configure --with-default-pid-dir
  - added configure --with-default-dm-run-dir
  - added configure --with-lvmetad-pidfile
  - by default, using one common pid directory for everything
    (only lvmetad was not following this before)

93945bb616 Use SD_ACTIVATION env. var. in systemd units to better detect systemd in use.
LISTEN_PID and LISTEN_FDS environment variables are defined only during systemd
"start" action. But we still need to know whether we're activated during
"reload" action as well - we use the reload action to call "dmeventd -R"/"lvmetad -R"
for statefull daemon restart. We can't use normal "restart" as that is simply
composed of "stop" and "start" and we would lose any state the daemon has.

aeb7a93796 Add 'Restart: on-abort' for lvmetad systemd service.
Restart lvmetad automatically if it exits due to reception of uncaught signal,
leaving a track in systemd log/syslog.

dac3c36feb Use DEFAULT_RUN_DIR instead of hardcoded value in lvmetad systemd units
and add ExecStartPost=vgscan to actually run the first scan that will
fill the metadata daemon with metadata information.
