qc_send_mux() has been extended previously to support pacing emission. This will ensure that no more than one datagram will be emitted during each invokation. However, to achieve better performance, it may be necessary to emit a batch of several datagrams one one turn. A so-called burst value can be specified by the user in the configuration. However, some congestion control algos may defined their owned dynamic value. As such, a new CC callback pacing_burst is defined. quic_cc_default_pacing_burst() can be used for algo without pacing interaction, such as cubic. It will returns a static value based on user selected configuration.
