I added a new permissions flag, CNV_NAME_REQD = 16777216 = 0x1000000, which
when set for a user in ftpusers, will require that user to invoke /name whenever
they use ax.25 mode to connect to the Jnos converse server.  This setting also
has the effect of allowing a flexnet node connecting via axip or ax.25 to join
as a converse node.  Thanks to Philippe F4CEP for concept and testing.

The following is a context-diff for patching recent Jnos versions through
1.11f.
