CLEANUP: mux-quic: rename internal functions

Browse Source 
This patch is similar to the previous one but for QUIC mux functions
used inside the mux code itself or application layer. Replace all
occurences of qc_* prefix by qcc_* or qcs_*. This should help to better
differentiate code between quic_conn and MUX.

This should be backported up to 2.7.
