GXemul Code2

Also try compiling with -std=c99 if compiling without first fails.

printf does not like dash as first char, since that means option.

Only invalidate the parts of the translation cache that are affected by CMMU_FLUSH_xxx commands. (No noticable performance difference though.)

OpenBSD/luna88k 6.8 -> 6.9 installation instructions (including ramdisk inode workaround).

Improved SMP stability by making sure to invalidate code translations for _all_ CPUs on memory writes, not just for the CPU doing the write.

Micro-optimizations.

More refactoring of breakpoints: internal support for printing instead of breaking, hits are now counted, CTRL-T prints breakpoint status etc. (No way to interactively configure all settings yet, though.)

The HD647180X is not yet implemented.

Use normal color also for the less-than sign (when printing symbols).

Minor updates: comments, debugmsg, int -> bool, etc.
