22cae20f02 server: Make sure CAP_CAP and CAP_TS6 are non-zero.
A zero CAP_CAP caused duplicate CAPAB to go undetected, allowing a
mismatch between what is sent out via ENCAP GCAP and what applies locally.

A zero CAP_TS6 allowed server connections without SID (with a valid
connect block).

5bd79c2c56 res.c: Try other servers if errors or corrupt replies are encountered.
Currently, the resolver treats SERVFAIL, NOTIMP, and REFUSED queries the
same as NXDOMAIN, but this really should not be the case. Instead, if
the DNS server errors on our request or provides an invalid request, try
another server.

Also, count DNS server errors in addition to timeouts and avoid these
undesirable servers.

ca4c2a86ee Add support for hookifying PRIVMSG/NOTICE.
This will allow us to modularize message processing, e.g. having new modules to manipulate
channel and private messages in new ways.

Yes: it can be used to intercept messages, but such modules are already out in the wild for
charybdis anyway -- so this doesn't really change anything there.

If you are changing the text, then it is your responsibility to provide a pointer to a new
buffer.  This buffer should be statically allocated and stored in your module's BSS segment.
We will not, and cannot, free your buffer in core, so dynamically allocated buffers will
cause a memory leak.

This will allow us to simplify m_message considerably, by moving channel mode logic out to
their own modules.

c74836dc4a Add explicit support for being installed into a system triggered with --enable-fhs-paths.
Add two mechanism for avoiding name-collisions in a system-wide
installation of charybdis. The ssld and bandb daemons, intended to be
directly used by ircd and not the user, install into libexec when
--enable-fhs-paths is set. For binaries which are meant to be in PATH
(bindir), such as ircd and viconf, there is now an option
--with-program-prefix=progprefix inspired by automake. If the user
specifies --with-program-prefix=charybdis, the ircd binary is named
charybdisircd when installed.

Add support for saving the pidfile to a rundir and storing the ban
database in localstatedir instead of in sysconfdir. This is, again,
conditional on --enable-fhs-paths.

Fix(?) genssl.sh to always write created SSL key/certificate/dh
parameters to the sysconfdir specified during ./configure. The
previous behavior was to assume that the user ran genssl.sh after
ensuring that his current working directory was either sysconfdir or a
sibling directory of sysconfdir.

d42e6915cf Pace aways.
This becomes important because of away-notify sending aways to common
channels much like nick changes (which are also paced).

Marking as unaway is not limited (but obviously only does something if the
user was away before). To allow users to fix typos in away messages, two
aways are allowed in sequence if away has not been used recently.

64b56afd8c Add a new dynamic capability manager.
Specifically, what this capability manager does, is map keywords to
calculated bitmasks.  These bitmasks are allocated at runtime, so that
the any managed capability index can be manipulated by modules.

Modules should call capability_orphan() when orphaning capabilities.  This
makes it so that bitmasks aren't reallocated, except for cases where the
capability is the same.

b583faf970 Add support for customizing the usable nick length.
This adds a new ISUPPORT token, NICKLEN_USABLE which is strictly an informative value.
NICKLEN is always the maximum runtime NICKLEN supported by the IRCd, as other servers may
have their own usable NICKLEN settings.  As NICKLEN_USABLE is strictly informative, and
NICKLEN is always the maximum possible NICKLEN, any clients which depend on NICKLEN for
memory preallocation will be unaffected by runtime changes to NICKLEN_USABLE.

The default NICKLEN is 50; the default serverinfo::nicklen in the config file is set to
30, which is the NICKLEN presently used on StaticBox.

nenolod gave the thumbs-up to port ircd-seven banfowards to charybdis to spb

slow weekend.

Note that as a side effect use_forward is removed from the config and

ae79dab6ae chanroles: grant initial set of flags to people added to a channel with CHFL_CHANOP.

8aabb973c0 Implement chanroles, as discussed with nenolod.
The theory behind this is that services sends an ENCAP * GRANT #channel
UID :+flagspec message specifying the chanroles the user has. They are
mapped into flag bits and applied to the membership of the user. They
then are restricted or permitted to what they can do based on the
permissions mask regardless of rank.

For backwards compatibility, the default permission bit (without a GRANT
statement) allows a user to to anything an existing op can do ONLY if
they are an op.

Todo: make CHANROLE_STATUS work (the ability to apply +ov to people),
which is at the moment controlled by CHANROLE_MODE.

19716b9fd6 New custom channel mode API allowing reloading such modules.
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.

431a1a2784 Add propagated klines.
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.
