7667f5f12f Add tests for generate_series(), and change an existing test that enforced varying rowid-to-value mapping with query ordering. (That no longer varies.)

baef8442d3 Further to [46639f682975dac6], the parameters of a table valued function that 
is on the left side of a RIGHT JOIN do not need to be in the ON clause.  Add
new test cases and tags to associated test cases with the code.

52576b78f6 Enhance the virtual table query planner so that it is able to deal with 
ORDER BY terms that contain COLLATE clauses as long as the specified
collation matches the virtual table.  This is especially important for
UNION ALL since a "COLLATE binary" is added to ORDER BY clauses if no
COLLATE clause exists in the original SQL.

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.
