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.

whois: check target is an oper before assuming they have a privset
The CHALLENGE functionality will set opername but not privset --
if an oper performs a WHOIS on someone currently half-way through
a challenge we will perform a NULL dereference.

f4d828ef96 m_alias: restore old behaviour of joining all parameters.
There are two important caveats here, however:

1) Aliased commands have more than 8 parameters will be truncated;
there's nothing I can do about this.
2) Parameters with colons will not be handled as you expect. Again,
nothing I can do about this.

Implement the netsplit batch type.
This also lays the groundwork for the netjoin batch type, but that isn't
implemented yet. I don't like how some of this is implemented but it'll
have to do for now...

Compile tested, needs more testing.

Change the way authd configures opm
It's a bit of a hack, but better than before. Rather than rehashing
(which could get us into an endless loop), we now segregate the
configuration phase (creating entries ircd-side in case we restart authd
later) and sending phases (when configure_authd() is called). Since we
have to call configure_authd() no matter what (to send timeouts etc.)
and we have to send this data to configure authd anyway, and sending
duplicate data is bad, this is the only way I can think of for now.

66f7fe673b Get rid of flags2.
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.

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.
