This patch removes flatfiles.c for good.
It doesn't change the keeping of locks in dbcommands.c and user.c,
because at least some of them are still required.
Regarding sync commits that previously happen and now won't, I think the
only case worth worrying about is the one in vacuum.c. Do we need a
ForceSyncCommit() in there? I'm not sure if vacuum itself already
forces sync commit.
