d1a720debd BuildROMs: Change name define logic to avoid conflicts 
Each of the BOOT_CODE_SIZE, BOOT_CODE_FILENAME and BOOT_CODE_ARRAY names
are replaced whenever a BuildROMs generated file is included.

ae1472db79 Generated ROM Image includes: Updated for multiple ROM image support 
The actual contents of the input ROM binary files and the contents of the
created arrays are unchanged.

Multiple ROM image include files can be included in the same source module
without the need for any #undef BOOT_CODE_SIZE, etc.

ae825c9afb All: Declare sim_stop_messages as an array SCPE_BASE long 
This avoids a potential invalid pointer dereference when formatting
the return value from sim_instr() if it is < SCPE_BASE but greater
than the previously defined static array size.sizeof

Update simh.doc to reflect this generic change.

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.

d0cee0f6b6 SWTP: Fixes to segfault issue described in #103 (from Gene Irwin) 
The simulated memory address block from 0x8000 thru 0x8FFF is defined to have address 0x8000 - 0x801F mapped to I/O ports and 0x8020 - 0x8FFF as NO RAM ALLOWED.  Code has been added to behave reasonably when references are made to 0x8020 - 0x8FFF.
