This changes the link anchors in "reference.html", from e.g.
`reference.html#pytest-current-test` to
`reference.html#envvar-PYTEST_CURRENT_TEST`, but I think that is OK, and
not worth adding labels for the old anchors.
Previously, writing to sys.stdout/stderr in text-mode (e.g.
`print('foo')`) while a `capsysbinary` fixture is active, would crash
with:
/usr/lib/python3.7/contextlib.py:119: in __exit__
next(self.gen)
E TypeError: write() argument must be str, not bytes
This is due to some confusion in the types. The relevant functions are
`snap()` and `writeorg()`. The function `snap()` returns what was
captured, and the return type should be `bytes` for the binary captures
and `str` for the regular ones. The `snap()` return value is eventually
passed to `writeorg()` to be written to the original file, so it's input
type should correspond to `snap()`. But this was incorrect for
`SysCaptureBinary`, which handled it like `str`.
To fix this, be explicit in the `snap()` and `writeorg()`
implementations, also of the other Capture types.
We can't add type annotations yet, because the current inheritance
scheme breaks Liskov Substitution and mypy would complain. To be
refactored later.

I tried to understand what the `safe_text_dupfile()` function and
`EncodedFile` class do. Outside tests, `EncodedFile` is only used by
`safe_text_dupfile`, and `safe_text_dupfile` is only used by
`FDCaptureBinary.__init__()`. I then started to eliminate always-true
conditions based on the single call site, and in the end nothing was
left except of a couple workarounds that are still needed.
The commit which added the checks for os.dup a15afb5e48
suggests it was done for Jython. But pytest doesn't support Jython
anymore (Jython is Python 2 only).
Furthermore, it looks like the faulthandler plugin (bundled in pytest
and enabled by default) uses os.dup() unprotected and there have not
been any complaints.
So seems better to just remove these checks, and only add if someone
with a legitimate use case complains.
`KeywordMapping` returns a bool on lookup which when passed to eval
fail on certain operations such as index access and attribute access.
We catch all exceptions and raise a `UsageError`.
When using `(i)var` in the class docstring it would link `duration` to
`_pytest.runner.TestReport.duration`.
This moves the docstrings to the attributes properly.
