5531ccb175 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.

92fe35fb9c PDP10: Fix nested indirect address limit exceeded (from Bob Supnik) 
If the nested indirect/execute limit (INDMAX, XCTMAX) is set to 0, the simulator will loop indefinitely in an indirect address or execute loop, testing for interrupts before each memory reference. Thus, on an infinite loop, the simulator will never complete the instruction, but the instruction is interruptible. So for example, under TOPS-10:

.r ddt
1/    0    jrstf @1
1$g
^C
^C
.

The JRSTF will never finish, but it can be interrupted by any device, and double ^C will return control to the command line.

If INDMAX or XCTMAX is non-zero, the previous behavior of limiting loops to a specific depth is retained. However, the default value is now 0.

This closes issue #218.

ed57f061e2 All VAX: Always return the correct Qbus/Unibus interrupt vector bits for all devices. Fix #239 
Vector values contained in device information blocks are the true bus relative vector values.  CPU specific biased vector values are produced by the respective vector fetching logic and vector values are limited to 9 bits with <1:0> = 0 as specified in both the Unibus and Qbus documents.

611a7e94f0 SCP: Added a Remote Console Master Mode. 
This capability will allow a GDB RSB stub to be created to support dynamic debugging of code running in a simulator.

This capability will also allow a complete front panel emulation system to operate a simulator.

This capability is engaged in a simulator by:
     sim> set remote telnet=remoteconsoleport#
     sim> set console telnet=consoleport#
     sim> set remote master

Master mode will provide a TCP session which accepts SCP commands that allow full control of the simulator.

6ce8d99cd8 SCP: Added generic output routine sim_printf to output to stdout and sim_log (and sim_deb when enabled) 
The goals here being to simplify calling code while getting consistent output delivered everywhere it may be useful.

Modified most places which explicitly used sim_log or merely called printf to now avoid doing that and merely call sim_printf().
