c398c65bee Revise the SQLITE_OPEN_NOFOLLOW so that it actually uses O_NOFOLLOW in the 
open() system call.  This backs out the SQLITE_ACCESS_SYMLINK value but adds
the new SQLITE_OK_SYMLINK return code from the xFullPathname method of 
sqlite3_vfs when that routine resolves symbolic links. O_NOFOLLOW is always
included in open() system calls for journal files.
