707821ff72 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.

fd748c6460 Split the SQLITE_WriteSchema flag in two flags, WriteSchema and 
SQLITE_NoSchemaError.  Set only WriteSchema on a VACUUM to avoid problems
when trying to vacuum a corrupt database.  With this change, the size
of the flags field on sqlite3 must grow from 32 to 64 bytes.
