This allows recovery after an IP address change (e.g. on dialup links).
Also move the update of "nextaction" timeout below the deadline check.

because otherwise the poll timeout will stay at SETTIME_TIMEOUT (15s)

The compression in lgetc() didn't happen for quoted strings,

Before this patch my test system's frequency adjustment would range
between -350 and +250, with timedelta rarely getting close to 0. After,
frequency adjustmens is on the order of +/- 0.05ppm, with time +/- a
few microseconds away from 0
