Fix the following two errors emitted by the Apple K&R C compiler
on Apple A/UX:
"./class.c", line 47: no automatic aggregate initialization
"./class.c", line 47: illegal lhs of assignment operator
"./conf.c", line 1052: syntax error
Tested on A/UX 3.1.1.
The cloaked IRC mask of a user is his visible mask, so the daemon has
to use it for generating the "one time" entries for the invite list of
the given channel.
Without this patch, ngIRCd records the real IRC mask which will never
match while the target client is "+x", and even worse, will disclose
the real mask on "MODE #channel +I" commands :-/

This fixes commit 2e168c78 ("Return ISUPPORT(005) numerics on
'VERSION'") and make sure, that the 005 numerics are correctly
routed back to the sender.
Don't support "range marching" in our pattern matching code using
the "[...]" syntax, because [ and ] are valid characters in nick
names and one has to quote them currently using the "\" character,
which is quite unexpected. For example:
Nick "te[st" => "MODE #channel +b te\[st"
And remove quoting altogether, too, because "*" and "?" don't need
to be quoted because these characters are not allowed in IRC masks,
nicks, and hostnames.

According to RFC 2812 3.2.3 "Channel mode message" and the examples
there, it looks like clients should use "MODE -k <key>" to unset channel
keys; and that's how other servers and services behave and do expect it.
(But please note that this is NOT the case for "MODE -l"!)
In the end, it doesn't make sense to specify a key when UNsetting it at
all, and different services behave diffrently when clients do not send
the currently set key to unset it - some ignore such calls, for example!
But this implementation is quite relaxed, it accepts any key when
unsetting channel mode "k" and even accepts no key at all. But the reply
will always include an "*" character for every "-k" parameter.
C99 states that vsnprintf() "returns the number of characters that
would have been printed if the n were unlimited"; but according to the
Linux manual page "glibc until 2.0.6 would return -1 when the output
was truncated" -- so we have to handle both cases ...
Test functions snprintf(), strlcpy(), strlcat(), vsnprintf() for
correctness, not only existance (which was quite useless, because
if they weren't available, the program could not have been linked
at all ...).
The new configuration variable "Network" is used to set the (completely
optional) "network name", to which this instance of the daemon belongs.
When set, this name is used in the ISUPPORT(005) numeric which is sent to
all clients connecting to the server after logging in.
Closes bug #165.
When DNS lookups are disabled, don't set the hostname received by the
WEBIRC command, but use the IP address instead.

Closes bug #167.
At least AIX 4.3.3 and 5.1 have a broken implementation of getaddrinfo()
which doesn't handle "0" as numeric service correctly. This patch adds
a configure check for this case and changes all calling functions to only
use getaddrinfo() if it "works".
See <http://www.stacken.kth.se/lists/heimdal-discuss/2004-05/msg00059.html>
Increase the penalty for a command before checking its arguments. This
makes the handling more consistent and allow us to move more penalties to
Handle_Request().
This fixes the following error when compiling without zlib support:
irc.c: In function ‘Option_String’:
irc.c:487: error: ‘options’ undeclared (first use in this function)

FreeBSD prior to 10.0 does not automatically stir on fork(). Same with
current NetBSD. If arc4random_stir() is present assume is needed and
call it instead of srand().
