- I wrote a thing: https://github.com/asottile/dead
- wanted to try it out, there's lots of false positives and I didn't look
  through all the things it pointed out but here's some

Remove some dead code

Merge master into features

* Remove non-standard testcase elements: 'file' and 'line'
* Replace testcase element 'skips' with 'skipped'
* Time resolution uses the standard format: 0.000
* Tests use corrected XML output with proper attributes

* "legacy" is no longer a copy of "xunit1"
* Attempts to use "legacy" will redirect to "xunit1"
* record_xml_attribute is not compatible outside of legacy family
* Replace call to method/override raw() with to_xml()

Regarding tests: it merges ``test_pdb_interaction``,
``test_pdb_print_captured_stdout``, and
``test_pdb_print_captured_stderr`` into
``test_pdb_print_captured_stdout_and_stderr`` (clarity and performance,
especially since pexpect tests are slow).
