  Log Message:
  -----------
  Changed mainloop end to run as long as one meter is running. (#388)

* Changed mainloop end to run as long as one meter is running.

MeterMap::stopped was returning wrong value if ::cancel was called
e.g. by a signal send from systemd.
Anyhow for multiple meters the mainloop was wrong so I changed it
to run as long as one meter is still running.
Issue: #385

* Cleanup of MeterMap cancel and stopped. Rework of mainloop.

Removed MeterMap::stopped. We should only use running() and cancel().
Reworked signal handler to call only async-signal-safe functions.
Reworked mainloop to check periodically whether it should stop
and indicate this to the meters by calling cancel().
