MFC r367640:

Explicitly note in the EXAMPLES section that uname(3) contains more details

MFC r319274:

- Add a simple example to uname(1) manual page to show how the hardware
platform (returned by -m) can be different from the machine's processor
architecture (-p)
- Document that make(1) sets universal MACHINE and MACHINE_ARCH variables
based on these values

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Change introduction history.

Add -K (__FreeBSD_version of kernel) and -U (__FreeBSD_version of userland).
Things like Makefile.inc1 resort to parsing /usr/include/osreldate.h with
awk because this isn't easily available by other means. The separation
of user and kernel versions is important for jail/chroot environments.

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

Add new -o option (r203042) to manpage synopsis and usage().

Submitted by: ru

Allow -o as a synonym for -s, for compatibility with other systems.

Using -s is preferred, but some existing scripts and makefiles expect
to get the system name from uname -o.

Sort sections.

Added the EXIT STATUS section where appropriate.

Fixed spelling of the document date.

Make kernel identification (`ident' in the config(8) driver) available to
userland, and the kernel. In the kernel by way of the 'ident[]' variable
akin to all the other stuff generated by newvers.sh. In userland it is
available to sysctl consumers via KERN_IDENT or 'kern.ident'. It is exported
by uname(1) by the -i flag.

Mostly rewrite the flag handling of uname(1) to be overridable, such as:
freefall% uname -s
FreeBSD
freefall% env UNAME_s=Linnex ./uname -s
Linnex

Note that this appeared at least as early as PWB UNIX.

Use the literal string 'PWB UNIX', as we still have no .At macro for it.

Note early appearence of some commands. These actually appeared in PWB, but
it seems we don't have a macro for that yet, so list them in the first UNIX
release since then that we have a .At for: v7.

mdoc(7) police: bump document date for the -p change, tidy up the markup.

'uname -p' prints the value of hw.machine_arch instead of hw.machine.

mdoc(7) police: utilize the new .Ex macro.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Add a -p option which is the same as the -m option but provided
for SVR4 compatibility.

Sort cross references.

Use the .Bx macro where appropriate.
