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.
.la archives are prohibited by most Linux distributions because they
clutter up the linker. They may get caught up as victims in scripts that
purge .la files. Besides, .la files don't matter for simple loadable
modules on most systems.
So, what we do now instead is just use the platform suffix detected by
libtool.
Purge a lot of really old and obsolete documents, and merge some together
where possible. Lots of efnet docs and the old ircd-ratbox manpage (lol)
was purged.
Reorganise everything nice and neatly as possible. Things describing
features can be found in features/, and some more technical documents
were moved to techinical/.
Old credits file was consolidated into credits-past.txt, and a reference
was added to it in the credits.
While functionally compatible with the implementation in ElementalIRCd, our approach is different,
specifically pre-calculating the bitmask at config load time. This is more efficient, and allows us
to report errors as part of the configuration phase.
This allows multiple improvements to m_sasl. With this change, the SASL
authentication gets aborted immediately when services are offline.
Additionally, we send the SASL ENCAP messages directly to the specified
SASL agent.
There are IPv4 and IPv6 ranges reserved for documentation and example code;
use these to minimize the risk if someone accidentally uses an unmodified
example conf.
