Bug#1081008: dump: Dump fails if the filesystem has more than 2^32 blocks

Package: dump
Version: 0.4b47-4+~tjw12r5
Severity: normal

Dear Maintainer,

Dump cannot handle more than 2^32 blocks. This was reported upstream
some years ago along with a patch that I am including here.

I'm reporting this as I have another ext4 patch that I've built on top
of this one.

I've also attached a testcase that doesn't require >12TB of data to
reproduce (it needs about 3GB of available disk space)

It's crafted to my setup and will require modification for anybody else
to use.
