One-line summary: Call check_expired_dcc() every second to honor -timeout settings

Additional description (if needed): This bug is ancient While at it, i made eof_timeout_dcc_ident() static

Test cases demonstrating functionality (if applicable): set ident-timeout 3 Configure your machine/network, so that ident requests of the bot will time out Then telnet to the bot check_expired_dcc() is executed every 10 seconds, so you will notice that the timeout will be longer than 3 seconds depending on the gap between the start of the timeout and the start of the check_expired_dcc() cycle
