- if the TCP quota has been exceeded but there are no clients listening for new connections on the interface, we can now force attachment to the quota using isc_quota_force(), instead of carrying on with the quota not attached. - the TCP client quota is now referenced via a reference-counted 'ns_tcpconn' object, one of which is created whenever a client begins listening for new connections, and attached to by members of that client's pipeline group. when the last reference to the tcpconn object is detached, it is freed and the TCP quota slot is released. - reduce code duplication by adding mark_tcp_active() function - convert counters to atomic (cherry picked from commit 7e822237) (cherry picked from commit 86a7d4c1)
