Prefix most of the preprocessor macros with `M68K_`

Use ptrdiff_t for pointer arithmetic results

Add a TRAP callback

Add a TRAP callback that allows interception & replacement of TRAP
instructions, so Musashi can be used for OS emulation.

Wrap m68kconf.h option #defines in #ifdef/#endif

Right now, users of Musashi generally need to incorporate it into their code,
rather than just reference it, because it’s necessary to supply a custom
`m68kconf.h` file for each use.

By wrapping the preprocessor macros to control the options in `#ifdef` and
`#endif`, these options can also be controlled without having to edit
`m68kconf.h` while still having reasonable defaults.

Prefix preprocessor macros with M68K_

Add prefixes to these preprocessor macros, so they’re properly namespaced like
the rest of the preprocessor macros are:

- `M68K_OPT_ON`
- `M68K_OPT_OFF`
- `M68K_OPT_SPECIFY_HANDLER`
- `M68K_ARRAY_LENGTH`

The `TRUE` and `FALSE` macros are kept as-is because they're so common in C
codebases and they're already properly protected from redefinition.
