In no particular order:

- As previously discussed, the "quic" option still implies "udp", 
  which is essentially a part of address.  Not sure what to do 
  with this.

- It looks like it would be possible to use non-QUIC name-based 
  virtual servers over QUIC.  Should we disable it (and return 
  421)?

- Some compatibility shims for previous configurations (not to be 
  merged into mainline, but might be useful for nginx-quic for a 
  while)?
