This header defines the TCP_NODELAY flag, which this compilation
unit uses.
Other C libraries implicitly include this header from some other
header we are using (I have not investigated which), but musl's
system headers do not, which breaks building on musl.

We remove characters like ^ and ~ from the ident string after checking
if it's valid. If it consisted entirely of those, we'd try to send an
empty string to ircd, which would break the protocol, so don't let that
happen.
This only supports two addresses as the intended use is 1 IPv4 and 1 IPv6
address on a single-homed host, and the only supported configuration of
outgoing connections to other servers is to bind a single IPv4 or IPv6
address.
Otherwise ident returns without setting itself running causing problems.
Move opm/blacklist before ident/rdns so that they can receive completion
notifications.
I run into this code even with a single kind of scanner with a single
port, so I'm not even sure how it thinks it already exists.
Perhaps it's being parsed twice, or something similar.

Iteration is the primary thing done on these, so using a dictionary
doesn't help a lot. Furthermore (and most importantly), they are not
safe to delete from.
It's a bit of a hack, but better than before. Rather than rehashing
(which could get us into an endless loop), we now segregate the
configuration phase (creating entries ircd-side in case we restart authd
later) and sending phases (when configure_authd() is called). Since we
have to call configure_authd() no matter what (to send timeouts etc.)
and we have to send this data to configure authd anyway, and sending
duplicate data is bad, this is the only way I can think of for now.
Clean up spaces/tabs mixing mess (bleh), add some defaults for authd
stuff, and get rid of CHARYBDIS_SOMAXCONN (just define SOMAXCONN if it's
available...).
Provider ID's are now assigned dynamically at load-time. To accomodate
this, there is now a lookup system for finding providers by name (all
providers have names as well).
Provider status (done, running, not run) is now attached to the
provider-specific data of the client. A reference count of auth
instances is kept in the auth_client struct to determine if a client is
done or not.
This also moves a lot of the logic for manipulating provider data into
into the provider.h header for inlining (no point in a function call for
these simple accessors).
