// This uses external interfaces to neqo_crypto rather than being a module
// inside of lib.rs. Because all other code uses the test_fixture module,
// they will be calling into the public version of init_db().  Calling into
// the version exposed to an inner module in lib.rs would result in calling
// a different version of init_db.  That causes explosions as they get
// different versions of the Once instance they use and they initialize NSS
// twice, probably likely in parallel.  That doesn't work out well.
