PR/30819: Peter Postma: src/usr.bin/shlock has no license

Thanks to Matt Fleming for contacting Erik E. Fair and getting his
agreement to put a TNF license on this.

PR/30820: Peter Postma: shlock(1) manpage incorrect

shlock uses link(2) rather than rename(2) to make the final target,
fix the manual page to reflect this.

Sort options; from Kouichirou Hiratsuka in PR 26256.

filesystem -> file system, writeable -> writable.

Use .Pp instead of empty lines, mark up AUHTORS section.

Whitespace cleanup.

The -v option actually is called -d.
Fixes PR 13168.

For commands and utilities, use EXIT STATUS rather than RETURN VALUES or
DIAGNOSTICS as appropriate (and documented in mdoc(7)).

PR/56112: Justin Parrott: Don't unlink a lock file without locking it, because
you can have races when multiple processes try to unlink it. Check the link
count to see if we have won the race.

While here:
- use snprintf
- use warn
- use size_t/ssize_t
- use loops instead of goto
- KNF

Fix casts which are inconsistent with *printf() formats and remove the
use of a non-standard type in the process.

Use pid_t directly. Apply static and __dead.

NULL does not need a cast
