modules: use exit(EXIT_FAILURE) on failure 
This will allow service process monitoring to recognise the difference
between a shutdown and an error of a -foreground ircd, because only
/DIE (or SIGINT) will exit with return code 0.

authd: wait until the ssl connection is "open" before reading 
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().

sslproc: use global ServerInfo configuration 
There's no need to pass information around that sslproc already has access

ircd: server connection configuration 
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.

ssld: Add new certfp_methods spki_sha256 and spki_sha512 
These operate on the SubjectPublicKeyInfo of the certificate, which does

Implement the netsplit batch type. 
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...

Change the way authd configures opm 
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.

a9b809c796 ircd_lexer: use correct variable here. 
ircd_paths[IRCD_PATH_ETC] is what's wanted, not IRCD_PATH_ETC.

This also does a lot of surgery on the conf system to reconfigure authd.

This allows things like oper warnings from authd using the W message type
also.

de7cf7e009 ircd: client: substantially rework the connid registry system 
now connid's are allocated on demand and clients may have as many connid's as necessary.
this allows us to build chains of helpers while ensuring the ircd properly tracks and GCs the resources.
