AltairZ80: Fix HALT stop code conflict with ON ERROR
...
AltairZ80 uses 0 for the VM-specific HLT instruction stop code.
SCP defines SCPE_OK as 0.
SCP uses 0 to mean all errors ("ON ERROR").
The command "ON 0" will generate "%SIM-ERROR: Invalid argument: 0".
This PR changes the HALT stop code from 0 to 5.

AltairZ80: Set conditional under CYGWIN so the SIMH device works
...
Under CYGWIN the conditional tests in the altairz80_sio.c source file for the
SIMH pseudo device's getHostsFilenamesCmd and resetSIMHInterfaceCmd
functions need to have UNIX_PLATFORM set to 1 - otherwise they do nothing!
With this fix, the HDIR host command from CP/M now displays a list of files
in host system's current directory under CYGWIN.

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.

Changed all internal #ifdef's which were conditional on __linux to be conditional on either __linux or __linux__. Some platforms (PPC) don't define __linux when gcc is invoked with -std=c99.
