drh c3927537d8 Disable the new malloc-37 test when locking_mode==exclusive. The test 
basically works, but sometimes reports "database is locked" instead of
"out of memory" and that messes up the error reporting. (CVS 6811)

drh 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)
