* Minimal support/stub layer that lets tests/test_sqlite_dbd.c link
* src/apps/relay/dbdrivers/dbd_sqlite.c in isolation, without dragging in the
* whole turnserver. It provides just the relay/server symbols the SQLite
* driver references: the userdb path accessor, the per-thread connection key,
* the hex->binary key conversion, and trivial implementations of the realm /
* secrets-list / origin-map helpers the driver calls into.
*
* The same stubs are used for both the old (string-interpolated) and the new
* (parameterized) driver, so any behavior difference the tests observe comes
* from the driver under test, not from this layer.
