Fixes to:
...
1) retain the buffered/unbuffered line specific details across save/restore
2) retain modem control outgoing bits (CTS and DTR) accross line resets which may occur due to carrier/connection loss.
3) change the behavior which sends the prior contents of the transmit buffer on a line reconnect to only happen for buffered telnet lines.
4) avoid crash in SHOW MULTIPLEXER output when only specific lines have been attached instead of

Added new tmxr_line_attach_string API to return the attach string specific to a a particular multiplexer line.
...
Added parsing logic to allow tcp port and connect strings to end in either ";notelnet" or ";telnet" as desired to specifically describe a port setup.
Fixed bug in single line multiplexer attach which returned failed status when it should not have if a tcp connect destination was specified.
Relaxed parsing rules to allow a single line multiplexer to have a listen port specified at either the line level or the mux level.
