Subject: ident.sh got a format string vuln fix. ident_service.sh will ident a
 service given its remote IP and port. (only run if ident is running on that
 remote computer) argc is just because I always forget what argc is for
 however many args. peereid is for unix sockets' ids peerip and sockip got the
 same upgrade. can now use the optional argv[1] to set the number of the file
 descriptor to use.
