You can now use "password" multiple times in the conf (eg in allow::password).

allow {
	mask *;
	password "secret";
	password "letmein";
}

This is always an "OR" type of match, any match means you pass.

I was actually doing this for the dual-cert stuff from previous commit,
where this can come in handy:

link irc1.example.org {
...
    password "AHMYBevUxXKU/S3pdBSjXP4zi4VOetYQQVJXoNYiBR0=" { spkifp; };
    password "jNw8P4QMg9tqjEJ4/lFikXBNHdIGSeN2B4/T322VjIo=" { spkifp; };
...
}
