libext2fs: openfs() musn't allow bigalloc without EXT2_FLAGS_64BITS
Currently, only the new 64-bit bitmap implementation supports the
block<->cluster conversions that bigalloc requires. Therefore, if we
have a bigalloc filesystem, require EXT2_FLAGS_64BITS be passed in to
ext2fs_open(). This does not mean that bigalloc file systems have to
be 64-bits; just that the userspace utilities have to be able to use
the new 64-bit capable library functions.
