Subject: Add InspIRCd::UseInterface and InspIRCd::DoneWithInterface, and also
 InspIRCd::GetInterfaceUseCount(). These can be used for one module to lock
 other modules in memory that it depends on, this way they can enforce an
 unload order so that you cant (for example) unload m_ssl_gnutls.so whilst
 m_spanningtree.so is using it for ssl server to server sessions (in this
 case, youd have to unload spanningtree first, THEN ssl_gnutls, to satisfy the
 dependencies and unload orders)
