shutdown: Remove unnecessary 2-second delay.

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.

Add missing static keywords for global variables to tools in sbin/.

These tools declare global variables without using the static keyword,
even though their use is limited to a single C-file, or without placing
an extern declaration of them in the proper header file.

For compatibility with Linux and Solaris add poweroff(8).

It is implemented as a hard link to shutdown(8) and it is equivalent of:

# shutdown -p now

While I'm here put one line of usage into one line of C code so it is easier to
grep(1) and separate unrelated code with empty line.

Signal init(8) instead of executing halt(8) or reboot(8)

Minor cleanups to shutdown(8):

- Make the -k "don't actually halt" flag incompatible with
the halt/reboot options -h, -p, and -r.
- The -n "don't sync" option is ignored if -k is specified.
Issue a warning message.
- Compute the actual shutdown time written to /var/run/nologin
correctly in the case of "now" being specified.

Fix a coredump with negative (due to overflow) offset values.

Move nologin from /etc to /var/run. This means one less file that has
to be written to /etc.

The only essential change is in paths.h, so any third-party software
written correctly will pick it up in the next rebuild.

Merged from Lite2 (one bcopy -> memmove, one significant change:

abnormally. NetBSD already has this change).

Merged from Lite2 (just an English fix or pun removal).

Correct use of .Nm. Add rcsid. Do not dot terminate err(3) strings. Spelling.

Pass an actual empty environment to execle() as per POSIX rather than

o Use a restricted environment.
o Improved error message when shutdown fails to exec reboot or halt.

Added environment parameter to execle calls.
