Add in the cost of doing a table lookup on OR searches. Make test case changes to deal with difference in STAT3 behavior. (check-in: d97898e8e3 user: drh tags: nextgen-query-plan-exp)

Only default HAVE_POSIX_FALLOCATE on for linux, and then only if it is not previously defined. (check-in: 2b2ade9278 user: drh tags: trunk)
