Deferred capability notifications from modules
Reloading modules sends CAP DEL followed by an immediate CAP NEW:

    :staberinde.local CAP * DEL :account-tag
    :staberinde.local CAP * NEW :account-tag

This isn't very nice. /modrestart is particularly bad. In order to avoid
doing this, we remember the capability set at the beginning of module
operations, compare that with the set afterwards, and report only the
differences with CAP {DEL,NEW}.

ircd: send tags on every message
Simplify linebuf by introducing fsnprint to manage a list of printfs.
Add a msgbuf unparse cache for send functions that loop.

ircd: check_server: don't allow a connection if that would exceed the class limit 2017-07-23 17:38:11 +01:00

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.

df0c70dd1f mr_server: Handle certificate validation errors.
When certificate validation fails, the certificate fingerprint won't be
calculated, resulting in an attempt to format NULL into a log line
showing the fingerprint. Instead, add a different error message for
missing fingerprint (i.e. validation failed).

echo-message should work for privmsg/notice to another user
Build the same message but send it to the local client first,
so that the echo-message capability works. But don't do it when
sending a message to yourself.

78946542bb modules: move module loading/unloading commands to dedicated module.
There's no reason to really have these in the main ircd anymore, static
modules are dead and aren't coming back.

To ensure people don't do something hopelessly retarded, this is a core
module.

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.
