Enhance the sqlite3_normalize_sql() interface so that it works even if the

prepared statement was not initially compiled using
SQLITE_PREPARE_NORMALIZED.  Enhance the ".trace" command in the CLI so that
it is able to access the full scope of functionality provided by 
sqlite3_trace_v2() and in particular so that it is able to show normalized
SQL output using the newly enhanced sqlite3_normalize_sql() interface.
