Improved signal handling to avoid deadlocks
- SIGSEGV: broadcast a message manually, avoiding the usual irc_write()
functions which are unsafe due to malloc().
- SIGTERM, SIGINT: Write to a pipe which gets handled in the main loop by
bitlbee_shutdown(), saving configs and stuff.
- SIGCHLD: set to ignore explicitly, which handles zombies correctly.
This also drops some log messages with 'info' level, which in practice
means they never got logged.
- SIGPIPE: set to ignore (nobody cares)
- SIGILL, SIGBUS, SIGFPE, SIGQUIT, SIGXCPU: Not handling anymore.
