Convert an OpenSSL library failure into a Python exception.
When a call to the native OpenSSL library fails, this is usually signalled
by the return value, and an error code is stored in an error queue
associated with the current thread. The err library provides functions to
obtain these error codes and textual error messages.

Convert a Python path to a :py:class:`bytes` for the path which can be
passed into an OpenSSL API accepting a filename.
:param s: A path (valid for os.fspath).
:return: An instance of :py:class:`bytes`.

If ``obj`` is text, emit a warning that it should be bytes instead and try
to convert it to bytes automatically.
:param str label: The name of the parameter from which ``obj`` was taken
(so a developer can easily find the source of the problem and correct
it).
:return: If ``obj`` is the text string type, a ``bytes`` object giving the
UTF-8 encoding of that text is returned. Otherwise, ``obj`` itself is
returned.
