logical order (1->2->3->4) rather than various helper functions first
and some random order.

changed by adjusting set::sasl-timeout, which should be (quite a bit)
less than set::handshake-timeout by the way. 15<30 now, so fine.

Also extban handler "is_ok" was being called with EXBTYPE_EXCEPT
rather than EXBTYPE_INVEX for +I. (Not reported by anyone)
deal with servers with different set::allowed-channelchars settings:
* We reject the link if set::allowed-channelchars settings differ between
UnrealIRCd 5 servers.
* For the case where you have a mixed network consisting of UnrealIRCd 4.x
and UnrealIRCd 5.x servers we try not to desync, BUT will not allow
anyone to join the invalid channels locally. For IRCOps a message is
printed with additional information on such a failed JOIN attempt.

CAN_SEND_TO_USER rather than HOOKTYPE_PRE_USERMSG (which is now removed).
As for the numeric change: this makes it much easier for client devs.
You rarely need to differentiate in the client code between the various
causes. One only cares about detecting that the message was not sent and
that the user needs to be informed.
This replaces various NOTICEs, ERR_NOCTCP, ERR_NONONREG etc. with just the
new numeric 531, which is taken from InspIRCd. The syntax is:
:server 531 yourname targetname :reason for the block
This makes it similar to numeric 404 (ERR_CANNOTSENDTOCHAN) that is used to
indicate that a channel message was blocked.
For module devs, the new hook CAN_SEND_TO_USER prototype is:
int hooktype_can_send_to_user(Client *client, Client *target, char **text, char **errmsg, int notice);
You can replace the text via this, by setting *text in your function.
You can block the message, by returning HOOK_DENY. If doing so, then
you must also set *errmsg to an appropriate value.
Do not send any error message to the user! UnrealIRCd will take care of
sending the error message for you, if you set *errmsg.
Only if you need something special you could violate this rule, but
preferably not!
As you can see, CAN_SEND_TO_USER works just like CAN_SEND_TO_CHANNEL.
1) HOOKTYPE_CAN_SEND is now called HOOKTYPE_CAN_SEND_TO_CHANNEL
The arguments and return values are unchanged
2) similarly can_send() is now called can_send_to_channel()
3) If you want to block or alter a message you must now
use HOOKTYPE_CAN_SEND_TO_CHANNEL and return HOOK_DENY from
there with an appropriate *errmsg filled (see nocolor and
many other modules for an example)
4) You CANNOT use HOOKTYPE_PRE_USERMSG anymore to block a message.
I actually wanted to rip this hooktype out entirely, but
delayjoin needs it. HOOKTYPE_PRE_USERMSG is only useful for
notification that a message is going to be sent BEFORE it is
actually sent (which is exactly what delayjoin needs, so it
can send a JOIN if the user is currently invisible).
5) This is all to make things more clean:
* HOOKTYPE_PRE_USERMSG is only for delayjoin
* HOOKTYPE_CAN_SEND_TO_CHANNEL is used for exactly what the
name implies. You can also change the message text there,
such as for +G, +S, etc.
