- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Another merging from sbin/fdisk/fdisk.8.

PR: 109929
Submitted by: Alex Kozlov

Reduce diffs against fdisk/fdisk.8.

- A partition number is allowed to 1-8.
- Remove non-exist -b flag.
- Add reference to boot98cfg and newfs.
- s/disklabel/bsdlabel/

Because there are so many more partitions on pc98 than on wintel (16
vs 4), supress all unused partition output unless -v is specified.
This makes operating on a 'typical' disk with one partition less
painful. The 30 lines needed for the empty partitions no longer
scroll the useful information off the screen. When the user requests
a specific partition, the unused information is not suppressed.

Also add the partition name to the -s output.

Initialize the partition name to 'FreeBSD' when -I is specified.

Markup fixes.

o Bump date (thanks ru)
o Also, fdisk_pc98 appears to support -i, so add it to the man page.
o Ditto -v
o Change the name from PC partition table maintenance program to NEC PC-98x1
partition table maintenance program, since it is possible to have a DOS MBR
formatted disk on FreeBSD/pc98 now (although we don't install any tools for
this).

Fixes and new features:
o Merge the -I switch from i386 verison to initialize the partition table
to use the maximum amount possible for a single FreeBSD table.
o Improve warning when the geom method fails (which I think it
always will until geom_pc98 is updated to respond to this ctl message)
o when writing out the boot sector, we have to write out a minimum of
1024 bytes or the sector size. This is different than the i386 case where
we need to write out a minimum of 512 bytes (which is also the minimum
sector size). We already handle this difference on reading, but didn't
in writing, so attempting to write a new partition table would fail.
o Add MID to the -s output, since pc98 users are likely interested in
both of these parameters.

# I can now initialize disks on my pc98 machine either by -I or by
# manually entering the parameters. I don't know if fdisk -B works or not,
# since I'm not willing to risk my only working boot disk to test it..
