m_cap: Fix CAP LS generation
The `caplen` variable was unused, so the cap to be output wasn't considered
when determining whether or not it would fit.

ircd: attach_conf: avoid clang static analysis warning

ircd: send_to_channel_flags: avoid clang static analysis warning
Set current_capmask and then use it, instead of referencing target_p->localClient->caps again.

This makes the purpose of current_capmask a bit clearer.

librb: commio: Must set addrlen before every call to accept()
If an IPv4 connection is dropped by the pre-callback, and there is a
pending IPv6 connection on the same listening socket then the retried
accept() will be unable to populate `st` because `addrlen` will be too
small. Also initialise `st` each time to avoid a clang static analysis
warning.

src/channel.c: don't use the bancache in is_banned()/is_quieted()

invalidation, but this is a good-enough temporary fix for issue #243

ircd: s_conf: fix use of strlcpy in strip_tabs
strlcpy should be called with the size of the destination buffer, not
the length of the source string.

When the source is an empty string, the destination buffer isn't
written at all, resulting in it trying to output uninitialised data.

This could also cause a buffer overflow on very long invalid config
lines.

GNUTLS: Provide a default priority string, disable TLSv1.0 in it
The user can still override this choice with the ssl_cipher_list option
in ircd.conf -- this is the only backend that will allow you to do so.

1175ff837d extensions/extb_channel: Allow matching secret channels.
This change modifies extb_channel to allow matching users in secret
channels, which prevents trivial ban evasion by setting the target
channel +s. Information leak due to this change is unlikely since the
attacker would have to know that the target channel exists, the name of
the channel (or guess it), have a specific user they wanted to know
whether was in the channel (and not know already), and the target user
would need to have something like autojoin-on-invite enabled (or any of
the other various ways hostname cloaking is attacked).

When a remote MODRESTART command is received, it will pass through the
ENCAP module. The ms_encap function is responsible for dispatching the
command handler and then the modules will eventually be reloaded.

However, if the ENCAP module is reloaded to a different address, the
stack now contains the address of a function that no longer exists.

Also, in this version of the IRCd, the module restarting functionality
was located in a function that is itself located in a module, so things
will also go badly if that module is reloaded to a different address,
too.

Return immediately from the command handler and have the event loop
call the function responsible for reloading the modules instead.
