This version leverages a flexible, cleaner key-value strategy
reducing the need to design entire new headers for every feature
addition, change, etc.
* A friendly declaration for the module authors, with minimal
requirements to fill in, and explicit labels of what the fields are.
* Repetition of keys, removing references to (and the requirement to
build) a clist, hlist and hfnlist and caplist and whatever the future
holds.
* Safe deterministic loading and unloading. Keys are evaluated in
order, errors can be recognized, and unloading occurs in reverse
order.
ircd: Refactor internal half of modules.c, with some V3 additions.
Provides better delegation for versions, a cleaner stack with better
error handling, and some functionality deduping. V1 and V2 handlers
are still somewhat unaltered, just factored in.
channel mode classification which is required by RPL_MYINFO indicating arity,
and RPL_ISUPPORT indicating an enumerated class. The content of these replies
had previously been generated by hardcoded strings of some letters.
Channel modes require classification which corresponds to the
CHANMODES= data in RPL_ISUPPORT. Classes A,B,C can then be
listed in the unary column of RPL_MYINFO. cflag_add() is updated
for this. Additional cleanup of chmode.h and channel.h
circularity is also proffered within.

It's useful to allow authd to run in parallel with ssl negotiation,
but if the ssld connection has plaintext data ready for reading
there's a race condition between authd calling read_packet() and
ssl_process_certfp() storing the certificate fingerprint. This
scenario would be bad for a server connecting because fingerprint
verification will fail.
Allow either operation to complete first, but wait until
ssl_process_open_fd() calls the ssl open callback before calling
read_packet().
Don't use the librb callback type as we're always passing client_p.
Provide a return value so that the connect handler can exit_client()
and the accept handler can opt to use the default dead handler.
There's no need to pass information around that sslproc already has access
to, so use ServerInfo directly. Remove the extra NULL checks as these are
already performed before setting ircd_ssl_ok = true.
Fix the server connection configuration so that it can simultaneously
handle a hostname/IPv4/IPv6 for connecting and a hostname/IPv4/IPv6
for binding. Maintains backwards compatibility for matching a hostname
with a mask.
Multiple host/vhost entries can be specified and the last value for
each address family is stored. Hostnames that resolve automatically
overwrite the IP address.
Server connections can now be made to either IPv4 or IPv6 at random
as well as preferring a specific address family.
This also lays the groundwork for the netjoin batch type, but that isn't
implemented yet. I don't like how some of this is implemented but it'll
have to do for now...
Compile tested, needs more testing.
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.
It seems to come from an era where long long didn't exist and 64-bit
machines weren't common. 32-bit machines are still common but I can't
imagine this will have much performance impact there.
This "fixes" #179 in title only, but see comments within.
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...).
There's no reason to really have these in the main ircd anymore, static
modules are dead and aren't coming back.
To ensure people don't do something hopelessly retarded, this is a core
module.
