Automatically clear any port fault after fifteen seconds.
...
The current port code is very defensive. As the code now stands, we throw
a fault whenever we cannot send or receive a packet. Even a downed link
on an interface will cause a port fault.
This commit adds a very simple minded way of clearing the faults. We just
try to enable the port again after waiting a bit.

This commit makes each pair of port functions, open/close and

...
In the course of development we added more and more allocations into the
port code without freeing them on close. We do not yet call the close
function, so there was never an issue. Once we start to reset the ports,
to clear faults for example, then we will need this.

We always wait for the transmit time stamp after sending an event message.

Fix segfault after missing transmit time stamp.
...
If the networking stack fails to provide a transmit time stamp, then we
might feed uninitialized stack data to the CMSG(3) macros. This can result
in a segfault or other badness.
The fix is to simply clear the control buffer in advance.
