ALL: Massive 'const' cleanup
...
These changes facilitate more robust parameter type checking and helps
to identify unexpected coding errors.
Most simulators can now also be compiled with a C++ compiler without
warnings.
Additionally, these changes have also been configured to facilitate easier
backporting of simulator and device simulation modules to run under the
simh v3.9+ SCP framework.

VAX: Move CPU register and routine declarations into vax_defs.h
...
Avoid redundant declarations in every simulator module that uses them
and allow compiler to validate consistency of declarations and definitions.

VAX, PDP11: Add support to, by default, limit console input data to about 9600bps.
...
This is necessary to avoid kernel type ahead buffer overruns when a user
pastes a chunk of data into a console session as described in issue #246
Other console input speeds can be set with SET CONSOLE SPEED=nnn

Change the semantics of sim_is_active to return a t_bool (which was 98% of how it was used), and added new sim_activate_time to return the time a unit will be activated (the value previously returned). This affected a handful of used of sim_is_active in device implementations which were adjusted to use the sim_activate_time API.

vax610_defs.h, vax610_stddev.c - Added SHOW CPU LEDS and SHOW CPU MODEL to the cpu_mod array using the CPU_MODEL_MODIFIERS #define.
...
- Added dynamic display of the LED values to the console port as the LEDs change during a boot.
