7e326c09c2 Make sure pParse->rc gets set whenever sqlite3ErrorMsg() is called. This is
added insurance that parsing will stop quickly after an error.  This change
did make the parser stop faster in some cases, which required some revisions
to tests. (CVS 4010)

c797d4dccd Begin implementing a new system of upper bounds on the capabilities
of SQLite.  By clearly defining the upper bounds, we make those
upper bounds explicitly testable.  This check-in is just infrastructure.

6c1426fd14 Get the column affinities right when processing an IN operator where
the right-hand side is a subquery with an ORDER BY clause.  Ticket #2295.
This bug has likely been present since version 3.0.0 and it has just now
been noticed, so it seems to be a obscure case. (CVS 3837)

is required. (CVS 3735)
