IEEE 1588 specifies dropping signaling messages if the
targetPortIdentity does not match the receiving port. Up until now
the unicast code did check that field, but only for the unicast
transmission request and cancel operations.
This patch moves the target port identity check so that it applies to
each and every received signaling message.

This patch adds new code that runs the state machine and handles the
TLVs for requesting unicast service from a remote master.
