Added to the e2fsprogs pu branch / 64-bit patch set.

BTW, note that this patch by itself caused the regression test suite
to explode spectactularly, since there was a number of printf-style
format statements that had to be changed so that dumpe2fs, debugfs
et. al, would work correctly after changing the above-mentioned
routines to return 32-bit values instead of 64-bit values.

I've fixed this before adding it to the e2fsprogs patch set.

Even though we do need to add more 64-bit tests, I do appreciate it if
people could test their patches using "make check" before sending
patches them to the ext4 list.
