e46ec734c7 Modify the generate_series() table-valued functions so that its first 
argument (the START value) is required.  Throw an error if that argument
is not supplied.  In this was the series.c loadable extension can be used
as a demonstration of how to code an xBestIndex function to require certain
parameters.  Compile with -DZERO_ARGUMENT_GENERATE_SERIES to obtain the
legacy behavior.

9196c81406 Eponymous virtual tables appear to exist in all schemas. This is an alternative 
and improved fix to the eponymous virtual table in trigger problem that
was previously addressed by checkin [1fa74930ab56171e].

'int64', 'double', or 'char*'.  'int32' is the default.
