It seems to come from an era where long long didn't exist and 64-bit
machines weren't common. 32-bit machines are still common but I can't
imagine this will have much performance impact there.
This "fixes" #179 in title only, but see comments within.
This also does a lot of surgery on the conf system to reconfigure authd.
/!\ WARNING! ACHTUNG! ADVERTENCIA! ATTENTION! AVVERTIMENTO! /!\
This code has not been run-time tested yet (though it compiles)!
now connid's are allocated on demand and clients may have as many connid's as necessary.
this allows us to build chains of helpers while ensuring the ircd properly tracks and GCs the resources.
this avoids race conditions when a file descriptor is reused and an ssld worker has not acked that the previous
connection was closed, which results in the new client being kicked.
Add the flags (auth{} spoof, dynamic spoof) to struct Whowas and add a
show_ip_whowas().
Normal users now see IPs of unspoofed users, and remote opers can see IPs
behind dynamic spoofs. Also, general::hide_spoof_ips is now applied when
the IP is shown, not when the client exits.
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.
* Deduce allow_read from the client's state (IsFloodDone) rather than
storing it in LocalUser.
* Fix the documentation (in oper /info), however strange
client_flood_burst_rate and client_flood_burst_max may seem, that is
how they currently work.
The extended-join client capability extends the JOIN message with information clients typically
query using WHO including accountname, signon TS and realname.
The code behind this capability was never implemented, and subsequent
discussions have agreed to approach the problem differently. There seems no
reason to continue advertising a capability that does nothing.
