Implement a limit per listener for concurrent number of QUIC connections. When reached, INITIAL packets for new connections are automatically dropped until the number of handshakes is reduced. The limit value is automatically based on listener backlog, which itself defaults to maxconn. This feature is important to ensure CPU and memory resources are not consume if too many handshakes attempt are started in parallel. Special care is taken if a connection is released before handshake completion. In this case, counter must be decremented. This forces to ensure that member <qc.state> is set early in qc_new_conn() before any quic_conn_release() invocation.
