of two or more joins where one of the joins to the right-hand side of the
list is a RIGHT or FULL JOIN.

remove the "or unsupported" clause, because we now support all valid join
types.

the right operand of a LEFT JOIN.

constraints on outer joins, and (3) ON/USING clause constraints on inner
joins. Formerly, there was no distinctionb between 1 and 3, but RIGHT JOIN
needs to know the difference. Make RIGHT JOIN aware of this difference and
add test cases.

"RightJoin" in the former name do not lead readers to believe that this has
something to do with RIGHT JOINs in particular.

make sure all its columns are flushed to NULL when it finishes so that
they appear to be NULL during the RIGHT JOIN post-processing.

the code to compute the unmatched rows for the RIGHT JOIN has not yet been
added, so the result of a RIGHT JOIN is currently the same as an INNER JOIN.

the same.

beyond SELECT statements. Should not affect deliverable builds.

Expr.w.iOfst field. This is done with the idea of providing offset
results for sqlite3_error_offset() for a more kinds of errors, though that
part is not yet implemented.

subquery has an ORDER BY clause and an OFFSET, NULL out the destination
register before starting the ORDER BY so that the register will be set
correctly even if the OFFSET is larger than the number of output rows.

opportunity to improve the isSimpleCount() function with better formatting,
an expanded header comment, and some extra assert() and textcase() macros.
