commit 217812fa9ec9417edbcafae90ec50402faacba96
Author: Daniel Stenberg <address@hidden>
AuthorDate: Wed Sep 25 12:27:26 2019 +0200

    ngtcp2: remove fprintf() calls
    
    - convert some of them to H3BUF() calls to infof()
    - remove some of them completely
    - made DEBUG_HTTP3 defined only if CURLDEBUG is set for now
    
    Closes #4421
