Standardizaton of TNC drivers structure among RMS software products.

A key weakness in deploying RMS functionality is cmpatiblity with TNCs.  Each RMS product has a slightly different TNC driver library with therefore inconsistent usage of TNCs across products (e.g. no simple KISS interface for RMS Express).

Depending on AGWPE is problematic both because of inconsistent behaviro of in particular RMS Packet with AGWPE, but also becuase AGWPE is inconsistenlty supported on oses.
