* does not apply to NOTICE (as those may well be automated)
* mirrors +g behaviour so that no useless accept entries are added for services
* respects max_accept, if it would be exceeded the message is dropped with numeric 494
* check moved up so this is checked before floodcount/tgchange
Pulled from Charybdis upstream changeset 1388:b1ef26176350 done by jilles.
Modeset files are modules stored in shadowircd/modes. All they do is initalize
a set of modes on load, and orphan said modes on unload.
All cmodes not included in ircd-ratbox are now located in modeset files, rather
than being in the core. These modes no longer simply use defines, their
locations are stored in a the new struct module_modes. Each of these is set
when intializing the mode in the modeset files, and set to 0 when orphaning
the mode upon unloading the modeset file.
In addition, use_forward has been removed, as it is now obsoleted by modesets.
to clients that don't send an ident and add a TODO item for 6.2 to
make ident timeout time configurable in the ircd.conf.
Currently it's only configurable in the include/defaults.h (ugly)
or on-the-fly with /set (doesn't persist, have to re-set it on each
restart/server).
Additionally, attempting to use too many modes or two times
the same letter is now detected and prevented.
Modules now request that a channel mode be added/orphaned,
instead of ugly manipulation from which that request had
to be guessed.
Slight changes are needed to modules that provide channel modes.
From the old API, one important function has been made static,
the other important function has been renamed, so loading old
modules should fail safely.
If this option is yes (default), KLINE by itself sets global (propagated) bans.
If this option is no, KLINE by itself sets a local kline following cluster{},
compatible with 3.2 and older versions.
Such bans are not applied locally, but are propagated normally.
They can only be removed on a server that applies them.
Note that normally KLINE will not accept such bans.
This is mainly for services, differing min_wildcard and
ircd changes.
A KLINE command without the ON clause now sets a propagated
("global") ban. KLINE commands with the ON clause work as
before.
Propagated klines can only be removed with an UNKLINE command
without the ON clause, and this removes them everywhere.
In fact, they remain in a deactivated state until the latest
expiry ever used for the mask has passed.
Propagated klines are part of the netburst using a new BAN
message and capab. If such a burst has an effect, both the
server name and the original oper are shown in the server
notice.
No checks whatsoever are done on bursted klines at this time.
The system should be extended to XLINE and RESV later.
There is currently no way to list propagated klines,
but TESTLINE works normally.
The value 0 indicates the creation time is unknown (currently the case
for bandb).
Also store a creation time for xlines and resvs, but do not use it yet.
