30d45ae7d9 AltairZ80: CPU: Properly reset PC. 
After adding the sim_clock_precalibrate_commands, the PC was not zero
at the sim> prompt after loading altairz80.

Set CPU_S to zero in cpu_reset to address this issue.

9fa55d0013 AltairZ80: M68K: Move Musashi to m68k directory. 
The M68K CPU is from https://github.com/kstenerud/Musashi.  Move into
its own directory to facilitate easier synchronization with upstream
Musashi.

d0c009504b AltairZ80: Add support for the AB Digital B810. 
The AB Digital Design B810 RAM card is a 256K Dynamic RAM card
with onboard refresh logic.  AltairZ80 support emulates four of
these cards for a total of 16 banks.

As used for the OASIS operating system, the B810 is configured
with common memory at the low addresses (0000h-3FFFh) with 16
banks of 48K from 4000h-FFFFh.

In order to have the common memory appear from 0000-3FFFh, set
the COMMONLOW register to 1:

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.
