The new linuxcncrsh server used v4-mapped-on-v6 to have one socket accept both IPv6 and IPv4 connections. However, if IPv6 is disabled at the kernel command line (or not compiled in), then it would fail to create a listening socket. Now there is a IPv4-only fallback in case IPv6 fails. This PR also fixes a lockup in the processing of SET commands when a client disconnects while a SET command is in flight.
