Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Widen fields that display partition offset/length.

This makes partitions between 50GiB and 2TiB (16TiB for 4k drives) print
correctly aligned.

While here, fix type of secsize. g_sectorsize() returns ssize_t, don't
store this in an unsigned var. Bump WARNS to 6.

MFC after: 4 weeks

Remove bsdlabel test-script that was full of broken assumptions.

- the default label now includes an a: partition by default
- the c: partition is no longer exported via devfs
- writing of the labels usually works in all cases, though the script
assumes half of them have to fail

Remove bsdlabel.5, which hasn't been installed in over 7 years
and contains little more than an out-dated copy of <sys/disklabel.h>

MFtbemd:

Prefer MACHNE_CPUARCH to MACHINE_ARCH in most contexts where you want
to test of all the CPUs of a given family conform.

Switch the default WARNS level for sbin/ to 6.

Remove alpha left-overs.

'-DPC98' is not needed.

Add amd64 to the MACHINE_ARCH list of systems that link bsdlabel to
disklabel. I just got burnt again by having an old disklabel binary
kicking around.

Compile bsdlabel on all platforms.

Install a link to the disklabel(8) name on i386 and alpha platforms.

Leave old disklabel(8) sources intact but disconnected from the build
for now.

Use new geom.ctl based OAM instead of ioctls.
Various cleanup.

Pull in geom_bsd_enc.c from sys/geom to encode and decode our labels.

Add the beginning of a regression test.

So far it checks the overwrites of the BSD label inband (ie: dd
if=/dev/ad0a of=/dev/ad2a).

This excercises the geom::slice::hotspot code.

First scrub of s/disklabel/bsdlabel/

bsdlabel.5 deliberately exempted, its contents looks less than useful.

Don't set WARNS to 2, we're default compatible now.

Noticed by: bde

Get us to WARNS=2 with a bit of constification and some printf fiddling.

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

Default to WARNS=2.
Binary builds that cannot handle this must explicitly set WARNS=0.

Fix style nit.

Turn dkcksum() into an __inline function.

Change its type to u_int_16_t.

Add '-DPC98' to CFLAGS if MACHINE == pc98.

Convert to our man installation style. Also fixed long-standing bug
in `fastboot'/`fasthalt' in which the interpreter would hang around
after `reboot' or `halt' is run, causing an irritating ``Killed'' message.

Remove stuff for building manual pages the old way.
