d3f6b80867 Replace s_auth/blacklist stuff with authd calls 
This also does a lot of surgery on the conf system to reconfigure authd.

de7cf7e009 ircd: client: substantially rework the connid registry system 
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.

3c7d6fcce7 Message handlers should return void. 
Also fix up some return values and stuff to use bool (or void if
nothing). I just did it whilst I was here.

According to jilles, the return value used to signify whether or not the
client had exited. This was error-prone and was fixed a long, long time
ago, but the return value was left int for historical reasons.

Since the return type is not used (and has no clear use case anyway),
it's safe to just get rid of it.

there's any problems, I apologise!

07554369bd Detect stdbool.h and add conformant shims if it isn't available 
Charybdis requires C99 already, so it's high time we start using
stdbool. I've converted a few pieces of code already.

A lot of the old code that uses YES/NO should probably be updated too
because that's fucking hideous.

394b8dde17 authd: allow querying the list of DNS servers. 
This was an asston of pain, and it still feels "dirty" as it introduces
an async call where there normally wouldn't be one. Better
implementation more than welcome.

a393a68a0e make build reproducible 
we do this by removing the uname usage everywhere: it is not actually
used at runtime at all.

we keep the timestamp, because it is actually used in user_welcome()
but allow it to be overriden.

ideally, that timestamp would be completely removed, but I am not sure
what to put in its place, or if it would break some mysterious RFC (or
client!) if we remove that announcement.

eb1b303d56 ircd: support restarting ssld processes 
Add REHASH SSLD (admins only) that starts new sslds and marks the
existing ones as inactive until all their clients disconnect.

Very useful whenever the SSL library has a vulnerability because
new connections can use a new version of the library without
disconnecting existing clients/servers.

Add STATS S (admins only) to list ssld processes, status, and client
count.

6eb0267a90 messages.h: Remove 900-902 IRCv3.1 SASL trailing period 
The IRCv3.1 SASL specification [1] has been updated today, and brings a
level of consistency with the trailing periods (or the lack of).

This implements the change made in
ircv3/ircv3-specifications@6d2ca77ffd.

e0160ec5a4 messages.h: Standardize 256 (RPL_ADMINME) with RFC 1459 
RPL_ADMINME is a response the client receives using the ADMIN command.
Charybdis used to implement a non-standard version of this.

The RFC 1459 standard [1] says in section "6.2 Command responses.":

            256     RPL_ADMINME
                            "<server> :Administrative info"

This commit corrects the behavior to follow the standard.

b5b4a0e79b client: use sequential connection ids for ssld connections in ssld RPC, instead of the file descriptor 
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.

63eb8567cb implement configurable channel modes (closes #31) 
While functionally compatible with the implementation in ElementalIRCd, our approach is different,
specifically pre-calculating the bitmask at config load time.  This is more efficient, and allows us
to report errors as part of the configuration phase.
