SimH simulator setup

Sometimes it is good to compare the w11a behavior with the PDP-11 software emulator from the SimH project. See INSTALL_simh for installation instructions and supported versions.

Under tools/simh two setup files are provided which configure SimH to reflect the w11a setup as closely as possible:

setup_w11a_min.scmd
Minimal configuration for low memory boards (as on s3board or Basys3)
- processor: 11/70, no FPP, 1 Mbyte
- periphery: 2 DL11, LP11, PC11, RK11/RK05
setup_w11a_max.scmd
Full configuration for the w11a, in addition
- processor: 4 Mbyte memory (as on Nexys and Arty type boards)
- periphery: in addition DZ11, RL11/RL02, RM70/RP06, TM11/TU10, DEUNA

Startup scripts are provided with each oskit. They usually call the w11a_max configuration and are used with

set up VT100 emulator window for 1st and 2nd DL11 and DZ11 lines depending on the capabilities of the started system
```
    console_starter -s -d DL0 &
    console_starter -s -d DL1 &
    console_starter -s -d DZ0 &
    console_starter -s -d DZ1 &
```
Note: the -s ensures that the port numbers used by SimH are taken!
the simulator is usually started with an .scmd command file, for oskits for example with
```
    cd $RETROBASE/tools/oskit/<oskit-name>
    pdp11 <oskit-name>_boot.scmd
```
