MINOR: cfgparse: enforce QUIC MUX compat on server line

Browse Source 
Add postparsing checks to control server line conformity regarding QUIC
both on the server address and the MUX protocol. An error is reported in
the following case :
* proto quic is explicitely specified but server address does not
  specify quic4/quic6 prefix
* another proto is explicitely specified but server address uses
  quic4/quic6 prefix
