Update coverage to 7.0.3

[pyup-bot]

This PR updates coverage from 6.5.0 to 7.0.3.

Changelog

7.0.3

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

- Fix: when using pytest-cov or pytest-xdist, or perhaps both, the combining
step could fail with ``assert row is not None`` using 7.0.2.  This was due to
a race condition that has always been possible and is still possible. In
7.0.1 and before, the error was silently swallowed by the combining code.
Now it will produce a message "Couldn't combine data file" and ignore the
data file as it used to do before 7.0.2.  Closes `issue 1522`_.

7.0.2

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

- Fix: when using the ``[run] relative_files = True`` setting, a relative
``[paths]`` pattern was still being made absolute.  This is now fixed,
closing `issue 1519`_.

- Fix: if Python doesn't provide tomllib, then TOML configuration files can
only be read if coverage.py is installed with the ``[toml]`` extra.
Coverage.py will raise an error if TOML support is not installed when it sees
your settings are in a .toml file. But it didn't understand that
``[tools.coverage]`` was a valid section header, so the error wasn't reported
if you used that header, and settings were silently ignored.  This is now
fixed, closing `issue 1516`_.

- Fix: adjusted how decorators are traced on PyPy 7.3.10, fixing `issue 1515`_.

- Fix: the ``coverage lcov`` report did not properly implement the
``--fail-under=MIN`` option.  This has been fixed.

- Refactor: added many type annotations, including a number of refactorings.
This should not affect outward behavior, but they were a bit invasive in some
places, so keep your eyes peeled for oddities.

- Refactor: removed the vestigial and long untested support for Jython and
IronPython.

7.0.1

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

- When checking if a file mapping resolved to a file that exists, we weren't
considering files in .whl files.  This is now fixed, closing `issue 1511`_.

- File pattern rules were too strict, forbidding plus signs and curly braces in
directory and file names.  This is now fixed, closing `issue 1513`_.

- Unusual Unicode or control characters in source files could prevent
reporting.  This is now fixed, closing `issue 1512`_.

- The PyPy wheel now installs on PyPy 3.7, 3.8, and 3.9, closing `issue 1510`_.

<changes_7-0-0b1_>`_.)

- Changes to file pattern matching, which might require updating your
configuration:

- Previously, ``*`` would incorrectly match directory separators, making
 precise matching difficult.  This is now fixed, closing `issue 1407`_.

- Now ``**`` matches any number of nested directories, including none.

- Improvements to combining data files when using the
:ref:`config_run_relative_files` setting:

- During ``coverage combine``, relative file paths are implicitly combined
 without needing a ``[paths]`` configuration setting.  This also fixed
 `issue 991`_.

- A ``[paths]`` setting like ``*/foo`` will now match ``foo/bar.py`` so that
 relative file paths can be combined more easily.

- The setting is properly interpreted in more places, fixing `issue 1280`_.

- Fixed environment variable expansion in pyproject.toml files.  It was overly
broad, causing errors outside of coverage.py settings, as described in `issue
1481`_ and `issue 1345`_.  This is now fixed, but in rare cases will require
changing your pyproject.toml to quote non-string values that use environment
substitution.

- Fixed internal logic that prevented coverage.py from running on
implementations other than CPython or PyPy (`issue 1474`_).

- Changes to file pattern matching, which might require updating your
configuration:

- Previously, ``*`` would incorrectly match directory separators, making
 precise matching difficult.  This is now fixed, closing `issue 1407`_.

- Now ``**`` matches any number of nested directories, including none.

- Improvements to combining data files when using the
:ref:`config_run_relative_files` setting, which might require updating your
configuration:

- During ``coverage combine``, relative file paths are implicitly combined
 without needing a ``[paths]`` configuration setting.  This also fixed
 `issue 991`_.

- A ``[paths]`` setting like ``*/foo`` will now match ``foo/bar.py`` so that
 relative file paths can be combined more easily.

- The :ref:`config_run_relative_files` setting is properly interpreted in
 more places, fixing `issue 1280`_.

- When remapping file paths with ``[paths]``, a path will be remapped only if
the resulting path exists.  The documentation has long said the prefix had to
exist, but it was never enforced.  This fixes `issue 608`_, improves `issue
649`_, and closes `issue 757`_.

- Reporting operations now implicitly use the ``[paths]`` setting to remap file
paths within a single data file.  Combining multiple files still requires the
``coverage combine`` step, but this simplifies some single-file situations.
Closes `issue 1212`_ and `issue 713`_.

- The ``coverage report`` command now has a ``--format=`` option.  The original
style is now ``--format=text``, and is the default.

- Using ``--format=markdown`` will write the table in Markdown format, thanks
 to `Steve Oswald <pull 1479_>`_, closing `issue 1418`_.

- Using ``--format=total`` will write a single total number to the
 output.  This can be useful for making badges or writing status updates.

- Combining data files with ``coverage combine`` now hashes the data files to
skip files that add no new information.  This can reduce the time needed.
Many details affect the speed-up, but for coverage.py's own test suite,
combining is about 40% faster. Closes `issue 1483`_.

- When searching for completely un-executed files, coverage.py uses the
presence of ``__init__.py`` files to determine which directories have source
that could have been imported.  However, `implicit namespace packages`_ don't
require ``__init__.py``.  A new setting ``[report]
include_namespace_packages`` tells coverage.py to consider these directories
during reporting.  Thanks to `Felix Horvat <pull 1387_>`_ for the
contribution.  Closes `issue 1383`_ and `issue 1024`_.

- Fixed environment variable expansion in pyproject.toml files.  It was overly
broad, causing errors outside of coverage.py settings, as described in `issue
1481`_ and `issue 1345`_.  This is now fixed, but in rare cases will require
changing your pyproject.toml to quote non-string values that use environment
substitution.

- An empty file has a coverage total of 100%, but used to fail with
``--fail-under``.  This has been fixed, closing `issue 1470`_.

- The text report table no longer writes out two separator lines if there are
no files listed in the table.  One is plenty.

- Fixed a mis-measurement of a strange use of wildcard alternatives in
match/case statements, closing `issue 1421`_.

- Fixed internal logic that prevented coverage.py from running on
implementations other than CPython or PyPy (`issue 1474`_).

- The deprecated ``[run] note`` setting has been completely removed.
