a015e44c10 ALL: Standardize writelock behavior adding global UNIT_WLK & UNIT_WPRT
Historically this functionality was reimplemented within each
DEVICE simulator often with slightly different implementations
and inconsistencies.  Solving this globally within SCP required
changes in many places, but should henceforth be reasonably
managed.

As discussed in #1034

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.

a9fd3dd518 Notes For V3.8
The makefile now works for Linux and most Unix's. However, for Solaris
and MacOS, you must first export the OSTYPE environment variable:

> export OSTYPE
> make

Otherwise, you will get build errors.

1. New Features

1.1 3.8-0

1.1.1 SCP and Libraries

- BREAK, NOBREAK, and SHOW BREAK with no argument will set, clear, and
  show (respectively) a breakpoint at the current PC.

1.1.2 GRI

- Added support for the GRI-99 processor.

1.1.3 HP2100

- Added support for the BACI terminal interface.
- Added support for RTE OS/VMA/EMA, SIGNAL, VIS firmware extensions.

1.1.4 Nova

- Added support for 64KW memory (implemented in third-party CPU's).

1.1.5 PDP-11

- Added support for DC11, RC11, KE11A, KG11A.
- Added modem control support for DL11.
- Added ASCII character support for all 8b devices.

1.2 3.8-1

1.2.1 SCP and libraries

- Added capability to set line connection order for terminal multiplexers.

1.2.2 HP2100

- Added support for 12620A/12936A privileged interrupt fence.
- Added support for 12792C eight-channel asynchronous multiplexer.

1.3 3.8-2

1.3.1 SCP and libraries

- Added line history capability for *nix hosts.
- Added "SHOW SHOW" and "SHOW <dev> SHOW" commands.

1.3.2 1401

- Added "no rewind" option to magtape boot.

1.3.3 PDP-11

- Added RD32 support to RQ
- Added debug support to RL

1.3.4 PDP-8

- Added FPP support (many thanks to Rick Murphy for debugging the code)

1.3.5 VAX-11/780

- Added AUTORESTART switch support, and VMS REBOOT command support
