Avoid all use of the "LL" suffix for long-long integer literals. Ticket #3759. (CVS 6408) (check-in: 7ef3693542 user: drh tags: trunk)

Another change related to (6401) and (6402): When an attempt to unlock a file fails in os_unix.c, close all files held open waiting for the unlock event anyway. This prevents a file-descriptor leak when testing IO errors. (CVS 6406) (check-in: 50fbcdea04 user: danielk1977 tags: trunk)
