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.

bb77b753c5 Enhance sqlite3_shutdown() so that it automatically invokes 
sqlite3_reset_auto_extension().  This is a harmless no-op if applications
are already calling sqlite3_reset_auto_extension() prior to sqlite3_shutdown().
And it prevents possible memory corruption if they do not.  So it works
either way.  Most of the changes are to the test cases. (CVS 6475)

ab7bee892b After running speed1.test and speed1p.test, reset the size of the lookaside buffer. Otherwise, subsequent runs of malloc5.test may report an error. Changes to test code only. (CVS 5824)

45c236d81e Add the speed1p.test script. Like speed1.test except that it tries to take 
advantage of prepared statements. (CVS 4907)
