When finding processes, ignore ourself and our ancestors. It is almost
always surprising when you kill a 'sh -c ...' ancestor or when you kill
yourself when using -f.

Improve the `pkill -t' handling, which I changed in my previous commit.

In my previous commit I disabled pkill(1)'s automatic prepending of the
"tty" string when `pkill -t' was being used. Re-enable it and stat()
both possible device names when called.

Requested by: jhb, rwatson (MFC)
MFC after: 1 month

Don't automatically prepend the "tty" prefix to `pkill -t' arguments.

Because we now enforce UNIX98-style PTY's, we now use a lot of TTY's
that don't have the traditional /dev/ttyXX naming scheme. pkill(1)'s -t
flag automatically prepended the word "tty" to each TTY that was passed
on the command line. This meant that `pkill -t pts/0' was actually
converted to /dev/ttypts/0. Disable this broken behaviour for now.

Reported by: erwin

pkill(1) first appeared in /usr/bin, but later it was moved to /bin
for the convenience of rc.d. Now it has happily lived there for quite
a while. So move the pkill(1) source files from usr.bin to bin, too.

Be more accurate in the description of the -I option:
signaling to a process doesn't necessarily kill it.

Fix and extend the -j option to pkill/pgrep WRT the jail
wildcard specifications. Earlier the only wildcard syntax
was "-j 0" for "any jail". There were at least
two shortcomings in it: First, jail ID 0 was abused; it
meant "no jail" in other utils, e.g., ps(1). Second, it
was impossible to match processed not in jail, which could
be useful to rc.d developers. Therefore a new syntax is
introduced: "-j any" means any jail while "-j none" means
out of jail. The old syntax is preserved for compatibility,
but now it's deprecated because it's limited and confusing.

Update the respective regression tests. While I'm here,
make the tests more complex but sensitive: Start several
processes, some in jail and some out of jail, so we can
detect that only the right processes are killed by pkill
or matched by pgrep.

-mdoc sweep.

I often find myself doing:

% pgrep <something> [to verify which processes match]
% pkill <something>

To speed such operation up, add -I option which works like rm(1)'s -i
option (unfortunately -i is already used in pkill(1)), ie. pkill will
ask for confirmation before killing each matching process.

After adding -j, -F, -i, -S, -o and -L options and other improvements,
I think I can add myself to the copyright header.

Revert previous behaviour of '-F' option and add '-L' option, which will
tell pkill(1)/pgrep(1) to try to flock(2) pidfile before reading PID from
there.

Discussed with: jhb, gad

Modify '-F' option to work nicely with pidfile(3) - a pidfile given as
an argument has to be locked.

Markup and wording fixes.

Approved by: re (blanket)

Whitespace fixes.

- Introduce an '-o' option which allows to match oldest of the matching
processes.
This option can be also found in Solaris and Linux.
- Use timercmp(9) macro for timeval comparsion.
- Include time.h directly, don't depend on stat.h doing it for us.

- Introduce '-S' option which allows to match system processes (pgrep only).
- Rename IS_KERNPROC() macro to PSKIP() and extend its functionality.
Now it'll skip calling process and system processes when -S is not given.
As a side effect it fixes '-n' option. Before it was always matching
calling process (because of missing 'if (kp->ki_pid == mypid)' check)
and after that, calling process was ignored.
- When '-l' option is given and there are no arguments, use p_comm as an
arguments list (this is helpful for kernel threads matching).

Don't forget the arguments for -M and -N in the DESCRIPTION section.

Added pgrep to the SYNOPSIS.
Fixed SYNOPSIS.
Fixed markup nits.

Avoid the manpage layering violation and low-level implementation
details of libkvm, and just tell what the getbootfile(3) function
will return, by using the text from netstat(1) and dmesg(8).

Correct the description of options -N and -M to match reality.

Add a comment for when these utilities were added to FreeBSD, and add
a cross-reference to killall(1).

Add `-M' and `-N' options to `pkill' and `pgrep', similar to
what are supported in `ps':

-M Extract values associated with the name list from the
specified core instead of the default /dev/kmem.
-N Extract the name list from the specified system instead
of the default /kernel.

Add the `pkill' and `pgrep' commands from NetBSD. This is the source
straight from NetBSD (except to add the RCS-ID lines for FreeBSD).
These will probably require a few updates before they are added to
the FreeBSD buildworld. I might MFC these to 4.x-stable after 4.10.
