Configurable transport parameters. - integer parameters can be configured using the following directives: quic_max_idle_timeout quic_max_ack_delay quic_max_packet_size quic_initial_max_data quic_initial_max_stream_data_bidi_local quic_initial_max_stream_data_bidi_remote quic_initial_max_stream_data_uni quic_initial_max_streams_bidi quic_initial_max_streams_uni quic_ack_delay_exponent quic_active_migration quic_active_connection_id_limit - only following parameters are actually sent: active_connection_id_limit initial_max_streams_uni initial_max_streams_bidi initial_max_stream_data_bidi_local initial_max_stream_data_bidi_remote initial_max_stream_data_uni (other parameters are to be added into ngx_quic_create_transport_params() function as needed, should be easy now) - draft 24 and draft 27 are now supported (at compile-time using quic_version macro)
