Spelling fixes for sbin/

Replace index() and rindex() calls with strchr() and strrchr().

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

Use in-label sectorsize to determine position of the label when
writing label into a file image. The most common use - putting disklabel
into ISO file. Before this change the label would always go to
the offset 512, while geom_part code expects it to be in the 1st
sector (i.e. 2048 incase of ISO). BSD disklabels provide good and
lightweight way to logically split livecds. It is non-intrusive as
far as ISO9660 goes (both boot-wise and metadata-wise) and
completely transparent to anything but BSD, so you can have
BSD-specific area appended after regular ISO.

And with a little bit of GEOM trickery you can do even more
interesting stuff with it.

For example we make "hybrid" bootable CDs using this method.
We create bootable ISO with kernel and such and append UFS
image compressed with UZIP and it works like a charm. We put
label based on the offsef of the BSD part into the ISO. The kernel
boots off normal ISO9660 part, tastes label attaches it,
tastes UZIP, attaches it and finally mounts UFS using GEOM_LABEL.
This provides much better way of eliminating waste than doing
"crunched" build.

Fix the derivation of the GEOM name from the specified device name by
complementing the existing special case of a not existing /dev prefix
with the recognition of an already existing /dev prefix.

This implicitly solves the following two issues related to working on
GEOM devices /dev/foo/bar (which have the GEOM provider name "foo/bar")
with the expected commands like "bsdlabel /dev/foo/bar":

1. the error "Geom not found" when trying to write or edit the BSD
label (because previously the incorrect GEOM name "bar" instead of
"foo/bar" was derived from "/dev/foo/bar").

2. the multiple times reported "magically introduced" partition offset
of 63 blocks and the resulting errors like "partition extends past
end of unit" and "partition c doesn't start at 0!".

This implicitly resulted because bsdlabel(8) determines the "MBR
offset" via GEOM and (intentionally) silently falls back to an offset
of 0 if it could not be queried (which is the case if the name was
incorrectly derived).

Usually (at least on PCs) the offset for the first slice is 63 blocks
and bsdlabel(8) automatically subtracts them from the absolute
offsets in the read on-disk BSD label, resulting in the display of an
effective offset of 0. If the GEOM query fails, the assumed offset of
0 is subtracted and an incorrect effective offset of 63 is displayed
and tried to be worked upon.

DISKTAB but not _PATH_DISKTAB).

Remove duplicate declarations for two internal functions.
Remove delcaration for getenv(), we already get it from stdlib.h

$Id$ -> $FreeBSD$

Minor style fix.

Various man page cleanup:

- Sort xrefs
- FreeBSD.ORG -> FreeBSD.org
- Properly xref RFCs.
- Be consistent with section names as outlined in mdoc(7).
- Other misc mdoc cleanup.

Remove inappropriate references to the wrong name for the bootstrap
manager, thus killing two birds with one stone.

Make intelligible:
Describe the command formats in English.
Add references to other programs (boot0cfg, fdisk).
Remove some old cruft, including FUD about single-level bootstraps.
Add example of output format.

Fix a gcc stupidity where it thought a variable was being used uninitialized

Add a case for UNSPEC which is in order by the enum definition, but out of
order alphabetically.

Update for boot block location change.

Look for boot blocks in new default location.

Refer to "da" rather than "sd" device.

Oops, don't quite use RAW_PART instead of RAWPARTITION. Use 'a' + RAW_PART
in both places.

Updated the error message for EXDEV to match recent kernel fixes.
Fixed nearby indentation.

Use RAW_PART instead of RAWPARTITION.

Attempt to fix my breakage of the alpha makebootarea() in rev.1.19.
The previous attempt just converted compile time breakage to runtime
breakage.

Try to make this compile on both alpha and i386

Fixed style bugs in previous commit.

Added some comments on #endifs.

Teach disklabel how to install a bootstrap on an alpha with SRM console.

Fixed bugs in `disklabel -R...':
- nonstandard sector sizes didn't work because the sector size in the
ASCII label was not read before a (default, wrong) sector size was used.
- the exit status was 0 after exiting early due to an invalid ASCII label.

Abort `disklabel -B...' if the secondary bootstrap doesn't fit.

Clear d_boot0 and d_boot1 in the virgin label. These are overlaid by
d_packname in in-core labels, so they are garbage if d_packname is
initialized in the dummy label for the whole disk. dsopen() will soon
initialize d_packname to "fictitious" if it is not already initialized.

Fixed nearby error handling. Rev.1.7 apparently confused Perror()
with perror().

Fixed printf format errors.

Use warnx()+fprintf() to handle multi-line messages. Correct K&R support and
KNF continuation indent rule.

Add section number to .Xr. Use of .Nm. Typo. Add rcsid. Remove unused
#includes. Use err(3).

Use the correct macro for file names. Remove empty `HISTORY' section.

Import Lite2's src/sbin, except for XNSrouted and routed. All relevant
files in src/sbin are off the vendor branch, so this doesn't change the
active versions.

Show the real revision date and not the date that this
manpage is being viewed.

Add Id. Use err(3). Costmetic in usage string.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Use mkstemp rather than mktemp to prevent a small race.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Sort cross references.

Moved initialization of defaults for the label for the whole disk from
disklabel(8) to the kernel (dsopen()). Drivers should initialize the
hardware values (rpm, interleave, skews). Drivers currently don't do
this, but it usually doesn't matter since rotational position stuff is
normally disabled.

Correct some man page cross references and file location references.

Try to preserve the fdisk table in the primary bootstrap, should it
already exist.

Mention the cases where this doesn't work in the BUGS section of the
man page.

Finally implement the "auto" disktype. It attempts to get all the
required information from the driver, and produce a virgin disklabel
for it. The latter might be further edited with `disklabel -e' to
satisfy the user's need.

The magic sequence is:

disklabel -r -w sdX auto
disklabel -e sdX

Declare functions, resolve printf-format warnings.

recording cvs-1.6 file death

Remove trailing whitespace.

Don't clobber d_secperunit in `disklabel -e'. `disklabel -e' replaces all
the values that it doesn't print by defaults. This seems wrong. I want
to be able to see the total number of sectors more than edit it. The
default d_secperunit of (sectors/track * tracks/cylinder * cylinders) is
bogus if sectors/track is only an approximation and more bogus if
sectors/track and tracks/cylinder are dummy values such as 4096 and 1
to defeat ufs's pessimizations.

Allow for the specification of bsize, fsize, and bps (blocks per segment)
for LFS filesystems.

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.
