Fix whitespace nits. Suggested by Bug Hunting.

Use more macros (Sq/Dq).

Add mechanism for escaping IPv6 address strings, since they already
contain colons. Idea from Solaris rcp(1).

- Support -4 and -6. Approved by christos.

Bump date for removal of Kerberos option descriptions.
Remove dots at end of SEE ALSO.

unavailable. Remove theses options from the man pages (it won't be very
hard to bring them back if we fix kerberos one day)

Patches provided by Joel Baker in PR 22249, verified by myself.

Add xrefs to new hosts.equiv(5)/rhosts(5) man page.

- Use ``.Nm ""'' instead of ``.Nm rcp'' in SYNOPSIS.
- Use ``.Nm "" .'' instead of ``.Nm rcp .''.

- cleanup use of .Nm in man page
- getopt returns -1 not EOF
