this fixes a problem where elf_mod_sizes() would report size which would
be different (smaller) that the actual size of LKM code to be loaded in some
cases

-w write in-core label if changed
-r update on-disk as well as in-core label (with -w)
-f force update (-w), even if there's been no change
-r behaviour suggested by matt green. what used to be `-f' is now `-wrf'
gotten bitten by mbrlabel trashing my incore disklabel to a point where
the machine wasn't usable, so I reworked it:
* only update the incore (and on-disk) label if `-f' is given. by default,
the proposed disklabel will be printed but no changes will occur
* add -q, to make the default operation a bit more quiet.
* leave existing `used' in-core partition slots alone, and only add entries
to the incore label if:
- there's not an existing partition of the same size and offset
(even of a different type)
- there's a free partition slot (`unused', with size == 0)
* use DIOCWDINFO instead of DIOCSDINFO, to update the incore as well as
the on-disk label
* use showpartitions() from ../disklabel/printlabel.c
this should make mbrlabel a *lot* more useful.
__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that. It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.

4 `slots', each of which can be another extended partition...
This involved reworking some of the internal functions.
* Use off_t appropriately (so we can manipulate sectors past 4GB).
* Tweak to compile with WARNS=2
