pointed out by bde:
- Ask for user confirmation before adjusting to a head/cylinder
boundary (only when running interactively), and separate this
adjustment from the automatic calculation of c/h/s parameters.
- In sanitize_partition, don't change any values in the slice until
we know that the automatic adjustment will succeed.
- When auto-adjusting, ignore unused slices and give an appropriate
error for other zero-size slices depending on the cause.
- Change dos() to do all of the c/h/s calculations for a whole slice;
this fixes a bug where the ending c/h/s of an unused slice was set
incorrectly.
- When changing the active slice, detect the currently active slice
number instead of always defaulting to slice 4.
- Call fflush(stdout) before calling fgets().
- Test for fgets() returning NULL so we don't loop on EOF.

device search code i introduce nearly six years ago in rev 1.8. Bruce
suggested to rather use the device name of the root filesystem instead
which is certainly the most sensible default. Since there are many
possible cases for a root filesystem name (device with and without
slices, consider /dev/vinum/root even though it currently could not
work as such), there's some heuristic using a RE in order to find out
the canonical device name from the mounted name. This probably won't
quite fit for a NFS root (can't test that right now), but then,
there's hard to find a good default for those machines anyway. ;-)
This unbreaks the functionality of rev 1.2 i once broke in 1.8. :)

prematurely terminate the search for a usable disk. ENOENT is quite
normal in particulare now with the advent of devfs.
While being here, also remove /dev/wd0 and /dev/od0 from the list of
disks to search since we don't have them anymore.

adjust the size, but the actual end.
- Break out some of the sanity checks on partitions into a sanitize_partition
function.
- When adjusting partitions, always adjust the start "up", and the end "down"
so that we stay within the boundaries of the original request.
- Various small nits found by bde.

some reason, mboot.bootinst is not initialized to NULL at the beginning
of the program, then the last commit to this would try to free whatever
bogus address is in it.
- Restore the behavior of free()'ing the mboot.bootinst buffer after we
abuse it to determine the sector size of the disk (as clearly noted in
the comments). Properly fix the double free() bug by setting the pointer
to NULL after we free it.

- Allow for MBR boot loaders that are longer than one sector. Only accept
boot loaders if their size is a multiple of the sector size, however.

This wipes the MBR and creates slice 1 as a FreeBSD slice covering the
disk starting from the second track to the cylinder aligned end of the disk.
This is the most compatibly layout we have as far as I know.

I don't have access to a BSD/OS machine to check the veracity of the
magic number. However, no harm will be done by the commit and since
someone was motivated enough to file a PR, I'm committing the change.
