This is aimed at creating floppies during cross-releases.
For different endianness machines, a tool like bswapfs(8)
is necessary to make the generated floppies readable on
the target machine. While here, fixed unaligned access
on Alphas.
Tested on: i386, alpha

Notable changes:
- Removed the "disktype" argument from the -B only synopsis
form. This form doesn't touch the disk label, and doesn't
use this argument.
- Fixed the first example in the EXAMPLES section. Support
for compatibility slices has been recently dropped from
the GEOM kernels, and a bit later GEOM became standard.
- Removed the buggy notion from rev. 1.37 that disklabel(8)
may be used to define mount points; it cannot. Improve
some DOS partition / FreeBSD slice wording. Among these,
``dangerously-dedicated slice'' was just a nonsense. ;-)

creates a single file named just "boot".
Apart from the fact that the option "-s" is now gone and that "-b" should
be pointed at /boot/boot instead of /boot/boot1, this patch should be
a no-op.

for the disklabel: This facility is OBE.
First of all, we cannot sensibly implement this in a properly stacked
environment.
Second, if we did, it would confuse the heck out of users who
wouldn't be able to "start from scratch" by dd(8)'ing /dev/zero
onto /dev/da0.
Third, the offered protection is not comprehensive: no other software
would respect it.
Fourth and finally, the disklabel is already protected against
tampering if it controls open partitions.

ascii label; otherwise checklabel() might report spurious errors because
of leftovers from a previous pass.

other partitiosns. This is necessary when migrating conventional
partitions to Vinum and was broken by recent more stringent overlap
checks. This is arguably the wrong way to do it. A better method
would be to have the loader understand a subset of Vinum partitioning
and allow an install directly to Vinum, but until then, this is the
best we have.

his allows one to label disk with the number of blocks > 31 bits
(though less then 32 bits)
e.g.
# size offset fstype [fsize bsize bps/cpg]
c: 3125755904 0 unused 0 0 # (Cyl. 0 - 194569*)
d: 3125755840 64 unused 0 0 # (Cyl. 0*- 194569*)

Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.
These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.
This commit adds a number of such #includes.
Once I have verified that I have fixed all the places which need fixing,
I will commit the updated versions of the three #include files.

that are used if none at all are specified for a partition. Don't
keep replaying the last field if we run out of fields when processing
a line. Use a 8:1 frag:block ratio for both defaults.
More work here is required. I think disklabel should not attempt
to choose default filesystem parameters, and instead let newfs pick
any defaults if required.

Pick up the c-partitions magicness from sys/disklabel.h instead
of defining our own magicness for it, remove trivial comment.
