33166dfcdf SCP: Fix potential multi threaded simulator activities when flushing log data 
Avoid the potential by properly leveraging the range that the
recursive mutex which already properly serializes separate activities
to the debug log file.

fed5342f44 SCP: CONSOLE Cleanup and DBGSIGNAL help 
- Add HELP language for SET CONSOLE DBGSIGNAL|NODBGSIGNAL.
- Remove obsolete sim_os_poll_kbd_ready platform specific routines
  which were only used with the never functional asynchronous TMXR
  code which has been otherwise removed everywhere else.
- Cleanup DBGSIGNAL related code comments

cbd8bd8a0a SCP : Log various initialization steps with DebugInit enabled 
Removed previously added DEPOSIT ALL 0 in precalibrate routine.
That DEPOSIT was added to explicitly restore memory to 0's at simulator
startup, but the several second cost of executing that slowed down
startup of any simulator which had precalibration support.  Anyone who
explicitly cares to have zeroed memory on startup should include such a
command in their own simulator configuration.
