34f7490311 Change the mmap_limit pragma to report the new limit, or to report the 
existing limit if called with no arguments.  Report the default mmap_limit
as part of PRAGMA compile_options.  Set the default mmmap_limit to 0 for
all systems other than linux, mac, windows, and solaris.

veryquick tests appear to work, however.

0d0614bdc6 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.
