Patch allowing to optionally run ntpdate at host resume time

When sleeping a host's hardware clock may wildly be drifing out of sync with UTC, ntp will correct that but it could take a few hours before the system time is again in synchronized. The proposed patch address this issue by optionally running ntpdate at resume time. While working on this I took the liberty to document the configuration variables used by the ntpdate rc script.

I forgot the disclose that I made this patch against 11-STABLE revision 345570.
Comment 2 Bertrand Petit 2019-04-02 11:41:48 UTC
Running ntpdate without no functional network interface is useless. Waiting for network availability is therefore important. I added a dependency on a patch that permit netwait to run at resume time.
