The offset (which is 64bits when mtd-utils are not compile with
WITHOUT_LARGEFILE) is calculated like that:
offset = nb * size;
But nb and size are int, so on 32bits platforms, there's a possible
overflow.
So, it should be replace with:
offset = (off_t)nb * size;
If WITHOUT_LARGEFILE is defined, there still be an overflow, but it's
what we want, right ?
Cheney Chen tested an ubiformat on a NAND (5.9 GiB mtd part).

The ubi-utils/src/ subdir is tossed as it just complicates things for no
real gain. The dictionary.h header is relocated to the ubi-utils/include/
since other headers in there need it.
The top level clean is replaced with a `find -delete` on objects, so it
might prune more than necessary, but many projects now do this sort of
thing and no one complained there.
A "mkdep" helper generates the actual rule, and the variables are used
with "foreach" to expand these automatically.
The tests subdir is updated only to reflect the ubi-utils source move.
Otherwise, it is left untouched as making that non-recursive isn't really
worth the effort.
While we're gutting things, also through in kbuild style output while
building to make things more legible.
