CON_CtrlHandler
The Windows Console doesn't use signals for terminating the application
with Ctrl-C, logging off, window closing, etc. Instead it uses a special
handler routine. Fortunately, the values for Ctrl signals don't seem to
overlap with true signal codes that Windows provides, so calling
Sys_SigHandler() with those numbers should be safe for generating unique
shutdown messages.
