[Greg Hudson via RT]

Modernize kerberos(7)

Update environment variable descriptions, using env_variables.rst as a
guide.  Replace the content in env_variables.rst with a pointer to
documentation at kerberos(7) so that we don't break external links and
don't duplicate content.

Replace references to rlogin.  Clarify and modernize other language.
