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) (check-in: 8fa33b79d7 user: danielk1977 tags: trunk)

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)

Test enhancements, especially to the new compound-SELECT merge logic. (CVS 5305) (check-in: edf7f51836 user: drh tags: trunk)
