f98109e7cb In the xUpdate method of the GeoPoly virtual table, make sure that the 
number of updated columns does not exceed the underlying implementation, even
if the virtual table object records an excess number of column in the nAux
field due to table constraints in the table definition.

d7480403bc Do not allow an ON clause to references tables to its right if there is a 
RIGHT or LEFT join anywhere in the query.  Other RDBMSes prohibit this always,
but SQLite must allow ON clauses to reference tables to their right for legacy
compatibility, unless there is a RIGHT or LEFT join someplace in the query,
in which case there is no legacy to support.
