MINOR: mux-quic: release idle conns on process stopping

Implement the idle frontend connection cleanup for QUIC mux. Each
connection is registered on the mux_stopping_list. On process closing,
the mux is notified via a new function qc_wake. This function immediatly
release the connection if the parent proxy is stopped.

This allows to quickly close the process even if there is QUIC
connection stucked on timeout.
