Summary of this patch:
[16/21] enlarge file size and filesystem size
- Add an option "-O large_block" in mke2fs.
- With this option, the maximum size of a file is (blocksize)
* (2^32-1) bytes, and of a filesystem is (pagesize) *
(2^32-1).

+.B large_block
+The maximum size of a file can be (blocksize)x(2^32-1) bytes and the maximum
+size of a filesystem is (pagesize)x(2^32-1). Specifically on 32 bit platforms,
+a file size cannot exceed 4TB. With this feature enabled, users cannot make
+blocksize smaller than 4KB.
