 Subject: [PATCH 133/139] dmeventd: unregister all devices on restart
 Instead of just exiting in the middle of monitoring,
 unregisted all monitored devices first and then exit.
 To speedup this path, all send internal SIGINT when thread
 unregiters itself, to wakup-up main sleeping loop.

 Subject: [PATCH 134/139] dmeventd: info status report
 To quickly get info about some internal dmeventd status,
 implment   'dmeventd -i' support.
 Reported messages are some 'raw' internal informations mainly
 useful to developers.

 Subject: [PATCH 137/139] dmeventd: implement exit_on file check
 When exit on file is present in a system and term/break signal is
 catched, them dmeventd is no longger refusing to exit.
 For the correct shutdown, there should be ideally unmonitoring call,
 however in some case it's very hard to implement this correct procedure.
 With this 'exit on' file dmeventd at least avoid 'blocking' shutdown,
 before systemd kills use with -9 anyway possibly even in some unwanted
 stated of internal dmeventd processing (i.e. in the middle of some lvm
 command processing).
