Richard Cochran 429c126b58 Select the system clock whenever legacy hardware time stamps are used.

Richard Cochran 56a5adc1cc Smooth the path delay estimate with a moving average. 
This is really just a first attempt using a hard coded length. Probably
it will be necessary to let the length be configurable and/or adaptable.

Richard Cochran 1d6737b75c Add a time out table for delay requests. 
We can pre-compute a table of suitable values in order to simplify the
run time random delay selection.

Richard Cochran 2fd7a1c18f Use the correct slave-only clock class. 
If we are going to be slave-only, then we should also advertise the
correct clock class.

Richard Cochran 5f7facdc63 Bind transmitted packets to the port's network interface. 
Even though the MCAST_JOIN_GROUP socket option includes the interface
index, this applies to the received packets only. To bind the outgoing
packets to a particular interface, the IP_MULTICAST_IF option is needed.

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.

Richard Cochran af380e8617 Add the license, a readme, and some header files. 
This commit gets the project off to a good start. The header files provide
some basic data types and definitions.

The README file will most probably grow over time.
