From: Joe Perches <joe@xxxxxxxxxxx>
Subject: get_maintainer: add more --self-test options

Add tests for duplicate section headers, missing section content, link and
scm reachability.

Miscellanea:

o Add --self-test=<foo> options
  (a comma separated list of any of sections, patterns, links or scm)
  where the default without options is all tests
o Rename check_maintainers_patterns to self_test
o Rename self_test_pattern_info to self_test_info
