59bfff4bfd TMXR: Make sure to only set UNIT_TM_POLL flag for active tmxr units. 
The effect here is to avoid clearing the UNIT_TM_POLL flag for devices which
call tmxr_set_line_unit or tmxr_set_line_output_unit on device reset.

584147fb64 TMXR: Remove output unit from delay consideration after poll has nothing queued 
The goal of the logic in _tmxr_activate_delay() is to properly schedule the next
poll activity considering input and/or output data rates that may be in effect.
We need to make sure that one more poll is scheduled after output data has
been sent since simulation logic may have deferred queuing output data for
other reasons and handles its reactivation in the same context that it polls for
output.

81bcd6d319 CONSOLE/SERIAL: Properly rate limit output to console port 
When the console is connected to a serial port or telnet sessions enable
speed setting, the bits being output are now paced a the desired speed.
Multi-line mux I/O is also correctly rate limited on all lines.

This should address the problems described in #545

305ce5b598 TMXR: Fix potential SegFault while negotiating telnet options 
If a telnet session sends options just prior to closing a session, the response
traffic might get dropped which isn't a problem, but we need to make sure
that we stop referencing the now invalid line structure after that happens.
