Consistenly use the pid_eq() and cid_eq() helper functions. Move the
functions into utils.h (making them inline functions) because they are
used in multiple source files.

The E2E TC forwards Announce, Delay_Req, Delay_Resp, Management,
Signaling, and Sync messages, and drops P2P Delay messages.
This implementation tracks the GM using the BMCA in order
to syntonize (or possibly even synchronize) with it.

This patch adds code that sends an event messages received on one port out
all the other ports and calculates the residence time. The correction,
ingress port, and the original message are remembered in a TC transmit
descriptor. These descriptors are recycled in a memory pool in a similar
way to the message buffers.

The transparent clock code will want to set qualification timeouts and
perform end to end delay measurements. This patch exposes the needed
methods.

When masterOnly is true, the port always returns NULL when computing
its best foreign master. As a result, the port will never enter the
SLAVE state, and the clock will ignore Announce messages received on
that port.
This attribute is specifically called out in G.8275.1 and G.8275.2,
and it is implied by the "master only" mode G.8265.1. In addition,
this option will probably appear in the next revision of IEEE 1588.

There is no need to keep two copies of the data set comparison
function. This patch adds a method that allows the port code to
obtain the function from the clock code.

This patch makes a number of subroutines into global functions in order
to share code with the TC implementations to come.

This patch places the internal port data structure into a common header
for use by the original BC and the new TC code.
