Implement regular event launching using systemd event loop
Regular events is made launch a timerfd event from binder event loop and then in the event handler, reschedule next launch in the future based upon the signal frequency. Change-Id: I0b1e84eb2135474f4bcc5ee256ba513eea4035a6 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
