Disable the use of memory-mapped I/O if the SQLITE_DISABLE_MMAP macro is
...
defined. Automatically define this macro for OpenBSD and QNX. Other
systems are likely to be added to the disabled list over time.

Memory-mapped I/O is now on by default. The "PRAGMA mmap_limit(N)" can be
...
used to issue a hint to the VFS to limit mmap space to N bytes. The VFS
is free to ignore that hint if desired. However, if "PRAGMA mmap_limit(0)"
is used, xFetch is never called.
