Richard Cochran 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.

Richard Cochran 29463cd306 Make the transport layer more opaque.
Although the UDP/IPv4 layer does not need any state per instance (other
than the two file descriptors), the raw Ethernet layer will need this.

Richard Cochran 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.

Richard Cochran 222c9bb62b Fix the port finite state machine.
The state machine needs to know whether a new master has just been
selected in order to choose between the slave and uncalibrated states.

Richard Cochran ba6cf8b767 uClinux: provide missing system calls.
The timerfd calls are missing from Sourcery CodeBench Lite 2011.09-23.
We can remove this code once these calls are properly integrated into a
current tool chain.

Richard Cochran ebd353aff6 Link it all together, but in slave-only mode.
Since the master implementation is still lacking, we will just keep
the slave-only flag hard coded for now.
