e9f86e320e introduce_client(): Remove redundant check for sockhost starting with colon.
Other code (inet_ntop6() in libratbox/src/commio.c and
extensions/m_webirc.c) ensures the sockhost does not start with a colon.
Checking only here does not make sense.

3881a3ce5d Don't append a domain to names without dot from reverse lookup.
Some code to append "domain" from /etc/resolv.conf to unqualified names (for
server connections) erroneously applied to names from reverse DNS lookups as
well.

The effect was that "domain" from /etc/resolv.conf was appended to
"localhost", even though the DNS server intended "localhost" to be a fully
qualified name.

624d779127 bandb: Don't apply empty ban list when bandb starts sending bans.
When bandb sends the ban list, it first sends 'C', then all bans and
finally 'F'. Only when 'F' is sent is ircd supposed to apply the bans.
Because of a missing break, 'C' also did 'F', clearing the ircd active
permanent bans until bandb sent 'F'.

The effect is pretty limited because having bandb send the ban list via
/rehash bans is uncommon and most bans will be enforced when reset.

aea6c4f9e6 chmode: Check mlock when a local oper changes cmode +L/+P.
This check was erroneously removed when fixing /mode #channel f when +f is
mlocked. Mlock checks were restricted to the places requiring chanops
(other than viewing +eI lists); cmode +L/+P do not require chanops, but
still constitute a mode change that must be checked against mlock.

This change prevents conf strings from being leaked when resetting the

are now rb_strdup'd into the ConfigFileEntry structure after loading the
conf so that they aren't allocated and then immediately freed by the
conf loading process.

dceac3e4fb conf parsing: Fix memory leaks and clean up code a bit.
Charybdis currently leaks about 45-50k per configuration parse,
including every rehash. This change plugs these leaks by properly
iterating through all conf_parm_t structures to seek all strings that
should be freed and also by freeing the conf_parm_t structures
themselves.

These leaks have been present since the original rewrite of the
configuration parsing system in ircd-ratbox r11953.

Additionally, this change also cleans up and documents the parsing code
a bit.

e1a9785abe Remove CHARSET=ascii from ISUPPORT
For one, [draft-brocklesby-irc-isupport-02][1] already defines "ascii" as the
default value. According to section 2 ("Except as
explicitly stated in its definition, a parameter should not be sent
unless it changes this default value, or the default value is vague,
badly defined, or differs between IRC server implementations"), there is
no point in sending it.

For another, [version 03 of the same draft][2] removes CHARSET ("It was
found to be unworkable;  a correct specification could not be devised to
represent its meaning across implementations."), and the token is not
present at all in [draft-hardy-irc-isupport-00][3].

77d3d2dbaf Remove s_assert definition from ircd_defs.h and add it to its own header.
s_assert requires some higher-level functionality that shouldn't be
present in ircd_defs.h. ircd_defs.h is used by ssld, which has no notion
of logging or sending IRC messages. Additionally, some of the headers
s_assert depends on result in conflicting definitions in ssld.c.

This change also fixes the compile when using --enable-assert=soft.
