Update coverage to 4.5.2

[pyup-bot]

This PR updates coverage from 4.4.1 to 4.5.2.

Changelog

4.5.1

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

- Now that 4.5 properly separated the ``[run] omit`` and ``[report] omit``
settings, an old bug has become apparent.  If you specified a package name
for ``[run] source``, then omit patterns weren't matched inside that package.
This bug (`issue 638`_) is now fixed.

- On Python 3.7, reporting about a decorated function with no body other than a
docstring would crash coverage.py with an IndexError (`issue 640`_).  This is
now fixed.

- Configurer plugins are now reported in the output of ``--debug=sys``.

4.5

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

- A new kind of plugin is supported: configurators are invoked at start-up to
allow more complex configuration than the .coveragerc file can easily do.
See :ref:`api_plugin` for details.  This solves the complex configuration
problem described in `issue 563`_.

- The ``fail_under`` option can now be a float.  Note that you must specify the
``[report] precision`` configuration option for the fractional part to be
used.  Thanks to Lars Hupfeldt Nielsen for help with the implementation.
Fixes `issue 631`_.

- The ``include`` and ``omit`` options can be specified for both the ``[run]``
and ``[report]`` phases of execution.  4.4.2 introduced some incorrect
interactions between those phases, where the options for one were confused
for the other.  This is now corrected, fixing `issue 621`_ and `issue 622`_.
Thanks to Daniel Hahler for seeing more clearly than I could.

- The ``coverage combine`` command used to always overwrite the data file, even
when no data had been read from apparently combinable files.  Now, an error
is raised if we thought there were files to combine, but in fact none of them
could be used.  Fixes `issue 629`_.

- The ``coverage combine`` command could get confused about path separators
when combining data collected on Windows with data collected on Linux, as
described in `issue 618`_.  This is now fixed: the result path always uses
the path separator specified in the ``[paths]`` result.

- On Windows, the HTML report could fail when source trees are deeply nested,
due to attempting to create HTML filenames longer than the 250-character
maximum.  Now filenames will never get much larger than 200 characters,
fixing `issue 627`_.  Thanks to Alex Sandro for helping with the fix.

4.4.2

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

- Support for Python 3.7.  In some cases, class and module docstrings are no
longer counted in statement totals, which could slightly change your total
results.

- Specifying both ``--source`` and ``--include`` no longer silently ignores the
include setting, instead it displays a warning. Thanks, Loïc Dachary.  Closes
`issue 265`_ and `issue 101`_.

- Fixed a race condition when saving data and multiple threads are tracing
(`issue 581`_). It could produce a "dictionary changed size during iteration"
RuntimeError.  I believe this mostly but not entirely fixes the race
condition.  A true fix would likely be too expensive.  Thanks, Peter Baughman
for the debugging, and Olivier Grisel for the fix with tests.

- Configuration values which are file paths will now apply tilde-expansion,
closing `issue 589`_.

- Now secondary config files like tox.ini and setup.cfg can be specified
explicitly, and prefixed sections like `[coverage:run]` will be read. Fixes
`issue 588`_.

- Be more flexible about the command name displayed by help, fixing
`issue 600`_. Thanks, Ben Finney.
