Subject: [PATCH] get_maintainer: Add a couple more --self-test options
Check for duplicate section headers and link reachability.
Miscellanea:
o Add --self-test=<foo> options (sections, patterns and scm for now)
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
