db: enable SQLite extended result codes

Browse Source 
With this change, we get more fine-grained error messages if something
goes wrong in the course of communicating with the SQLite database. To
pick some random examples, the error codes SQLITE_IOERR_NOMEM,
SQLITE_IOERR_CORRUPTFS or SQLITE_IOERR_FSYNC are way more specific
than just a plain SQLITE_IOERR, and the corresponding error messages
generated by sqlite3_errstr() will hence give a better hint to the
user (or also to the developers, if an error report is sent) what the
cause for a failure is.
