Just a warning... both of these controls get fairly involved.

This, of course, is a problematic assumption.  Many LDAPv2+ clients
send non-bind operations as their first request.  However, for the
average request, it's impossible to determine if client is LDAPv2+
or LDAPv3 and the server very likely needs to known this to respond
properly.

Forcing the protocol version to 3 will break a fair number of LDAPv2
clients.  However, I see no reasonable alternative.  I'll commit
the necessary changes in a bit.
