b35c8f287d Take the "tickadj" element out of struct clockinfo. Our adjtime(2)
implementation is being changed and the very concept of tickadj will
no longer be meaningful.

617cc038bc Document the existence of machdep.guessed_bootdev, as suggested
by Sheldon.
For a detailed description look at the commit log for sysctl.c
rev.1.42 -- i do not think it is appropriate to put the full
description in this manpage, and the "boot" and "loader" manpages
where this description might go are also missing a description of
a number of similar variables, so i think this it is ok to limit
documentation to this now, and update it later when I (or someone
else) have a chance to revise "boot" and "loader".

60cf2c1254 Export a (machine dependent) kernel variable bootdev as
machdep.guessed_bootdev, and add code to sysctl to parse its value
and give a (not necessarily correct) name to the device we booted
from (the main motivation for this code is to use the info in the
PicoBSD boot scripts, and the impact on the kernel is minimal).

NOTE: the information available in bootdev is not always reliable,
so you should not trust it too much.  The parsing code is the same
as in boot2.c, and cannot cover all cases -- as it is, it seems to
work fine with floppies and IDE disks recognised by the BIOS. It
_should_ work as well with SCSI disks recognised by the BIOS.
Booting from a CDROM in floppy emulation will return /dev/fd0 (because
this is what the BIOS tells us).
Booting off the network (e.g. with etherboot) leaves bootdev unset so
the value will be printed as "invalid (0xffffffff)".

Finally, this feature might go away at some point, hopefully when we
have a more reliable way to get the same information.

d58f005463 Allow setting of variables of type dev_t by indicating the name of
a special file on the command line, eg:
  sysctl kern.dumpdev=/dev/ad1s1b

In parse(), when a value is given for a CTLTYPE_QUAD variable,
newval and newsize erroneously fail to be set because of an early
"break".

show_var() contains code that duplicates the functionality of the
oidfmt() function.

6105f81565 Add code to export and print the description associated to sysctl
variables. Use the -d flag in sysctl(8) to see this information.

Possible extensions to sysctl:
 + report variables that do not have a description
 + given a name, report the oid it maps to.

Note to developers: have a look at your code, there are a number of
	variables which do not have a description.

Note to developers: do we want this in 4.5 ? It is a very small change
	and very useful for documentation purposes.

d0b8aabb19 Implement -e option. It modifies the output produced by sysctl(8) in
such a way that the name and the value of the variable(s) are separated
with `=' instead of the usual `: '.  This is useful for producing output
that can be fed back to the sysctl utility (pasted to sysctl.conf, for
example).

369a22fab1 Remove xref to blackhole(4). sysctl has nothing to do with
blackhole(4), except that blackhole(4) uses sysctl's.  This xref
obviously isn't appropriate unless we want to xref all the other man
pages which mention sysctls, which we obviously don't (we may want to
list those sysctls, but that's another story).

9a2402bc41 Try to make sysctl options slightly more orthogonal:
- introduce a -o option that displays opaque variables.
 - introduce a -x option that displays opaque variables in full.
 - deprecate -A in favor of -ao and -X in favor of -ax.
 - remove -A and -X from usage() and SYNOPSIS (but not from DESCRIPTION).
 - ignore -a if one or more variables were listed on the command line.
 - deprecate -w, it is not needed to determine the user's intentions.
 - some language and style cleanup in the man page.

This commit should not break any existing scripts.
