[pyup-bot]

This PR updates coverage from 5.3 to 5.3.1.

Changelog

5.3.1

----------------------------

- When using ``--source`` on a large source tree, v5.x was slower than previous
versions.  This performance regression is now fixed, closing `issue 1037`_.

- Mysterious SQLite errors can happen on PyPy, as reported in `issue 1010`_. An
immediate retry seems to fix the problem, although it is an unsatisfying
solution.

- The HTML report now saves the sort order in a more widely supported way,
fixing `issue 986`_.  Thanks, Sebastián Ramírez (`pull request 1066`_).

- The HTML report pages now have a :ref:`Sleepy Snake <sleepy>` favicon.

- Wheels are now provided for manylinux2010, and for PyPy3 (pp36 and pp37).

- Continuous integration has moved from Travis and AppVeyor to GitHub Actions.
