f2ffeae0f4 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.

2607806579 Rationalize the port reset logic. 
This commit makes each pair of port functions, open/close and
initialize/disable, balance each other in how they allocate or free
resources. This change lays some ground work to allow proper fault
handling and disable/enable logic later on.

0ca8143da5 Remove a useless variable from the file descriptor array data type. 
It was a cute idea to have the raw Ethernet layer use just one socket,
but it ended up not working on some specific PTP time stamping hardware.

9c9dc35f13 Clean up dynamic fields when closing a port. 
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.

5f0c034494 Throw an error at the port level on missing transmit time stamps. 
We always wait for the transmit time stamp after sending an event message.
Thus a missing time stamp is clearly a fault, even if the hardware can
only handle one time stamp at a time.

a9e88a0a49 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.

150da0cba9 Remove silly and incorrect error message. 
Commit 32133050 introduced a bug that gives a bogus error message on
every 'general' (non-event) PTP packet. If we want to catch missing
time stamps, then it has to occur at the port level.
