Whilst working on a new video device I ran into a few problems with the
LKxxx keyboard and I noticed there are already some open issues against
the keyboard and mouse devices. These changes should resolve#320 and
may help with #272 (although I think that is an SDL issue). I've tested these
changes with VWS, UWS and DECwindows with both captured and
uncaptured input modes.
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.
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().
