Added some new dosmod communication possibilities, including
activating a dosmod-specific setitimer(), and the capture of some
common signals, which is returned to Wine (previously a SIGILL
would just cause a "dosmod sync lost" without explanation, now it
invokes the Wine debugger). Invokes int 08 upon receipt of dosmod
SIGALRM, thus simulating the DOS timer. Made DOS interrupt calls
be reported by -debugmsg +relay instead of -debugmsg +int. And
fixed non-i386 compilation of dosmod. (Anything else?!)
