Overview
Comment:Remove internal function sqlite3OsDefaultVfs(). The built-in VFS layers now register their VFS implementations by calling sqlite3_vfs_register() from within sqlite3_os_init(). (CVS 5307)

Change the makefiles so that "make test" now runs the veryquick.test script instead of quick.test. Also modify veryquick.test to reuse the code in quick.test. veryquick.test is now the same as quick.test except that it omits all testing related to malloc and IO error simulation.

Have mem3.c and mem5.c grab a mutex when required. Include them both in the amalgamation again. (CVS 5306) (check-in: 9e3c95ff40 user: danielk1977 tags: trunk)
