I've committed most of this patch, with some modifications. In
particular, I moved CachedPlanSource's hasForeignJoin flag to the
CachedPlan and renamed it has_foreign_join, consistent with the naming
of other members.

The GetUserMappingById() function seemed like a separate thing, so I
left that out of this commit.
