Do not attempt to use the sub-journal file descriptor if it is not opened (as in journal_mode=off mode). Ticket #3636. (CVS 6252) check-in: 20bd7605 user: danielk1977 tags: trunk

Changes to completely remove all floating point ops if SQLITE_OMIT_FLOATING_POINT defined. Note that w/o fp, date/time, round, nan, etc. are all gone or limited in functionality. Updated some of the test scripts to support missing fp and 64-bit functionality. Ticket #3029. (CVS 6250) check-in: 5cef4000 user: shane tags: trunk
