If a user who is currently logged in to WebMods is deleted, his CWebSession
still kept a stale CUser pointer around. The next time he loaded a web page,
Bad Things(tm) happened.
This is fixed by deleting all of a user's sessions when that user is deleted.
Thanks to DarthGandalf for spotting the bug and writing the patch.

When a CWebSock was destroyed before its CWebAuth, the CWebAuth dereferenced a
stale pointer once it was used again. Fix this by calling
CAuthBase::Invalidate() appropriately.
Thanks to DarthGandalf for finding this.

The traffic generated by it was just discarded. Now it's accounted towards a
user if one is logged in, else towards the global traffic usage.

WebModules use CHTTPSock for the HTTP server. That class requires a CModule
instance for working since it's based on CSocket. This was solved by creating a
fake module instance which is destroyed when the socket is destroyed.
The problem here was that CSocket's destructor tried to access that module
instance which was already destroyed resulting in a use-after-free.

Now that we have the new ServerThrottle, we should be able to live with this
higher connect rate. Connecting lots of users is still awfully slow. :(

We now use a lot more data for generating the session id which is fed to a hash
to make it impossible to attack specific parts of the input.
Also we now retry generating a new session id in the (improbable) case of
collision with an existing session id.
Thanks a lot to cnu for pointing out the weakness in the old code by stealing my
session cookie, you evil hacker!

The old code only worked when the CSmartPtr instance was at the left side of the
comparison and comparing two CSmartPtr directly resulted in a compiler error.

Before this, --makeconf used "Listen" if you said "no" to "do you want ipv6?"
and "Listen6" else. Since yesterday, "Listen" means "v4 and v6 please" (thanks
to DarthGandalg) which means we now use "Listen4" for "no" and "Listen" else.

"Listen6" and "Listen4" now do what the name implies and "Listen" listens on
both ipv4 and ipv6 (unless a bind host was set which forces something
different).
This also changes webadmin appropriately.
Thanks to DarthGandalf for the idea and the patch.

Instead of just time() (which can be easily guessed by an attacker when he gets
a couple of samples of rand() results), this now also uses the current
microseconds, znc's pid and the old PRNG state for computing a seed.

This adds support for the general CAP protocol and the multi-prefix and
userhost-in-names (NAMESX and UHNAMES) to znc. There is no module call for CAP
tokens yet, but if modules really want to "catch" capabilities, we should most
likely add one.

Before, route_replies bypassed this function which caused "wrong" replies to
/names, because clients who didnt understand it still got NAMESX and UHNAMES
replies.
