* Add name and mode attributes for compressed and archived file-like objects
in modules bz2, lzma, tarfile and zipfile.
* Change the value of the mode attribute of GzipFile from integer (1 or 2)
to string ('rb' or 'wb').
* Change the value of the mode attribute of ZipExtFile from 'r' to 'rb'.
* Increase coverage for compressed file-like objects initialized with a
file name, an open file object, a file object opened by file
descriptor, and a file-like object without name and mode attributes
(io.BytesIO)
* Increase coverage for name, fileno(), mode, readable(), writable(),
seekable() in different modes and states
* No longer skip tests with bytes names
* Test objects implementing the path protocol, not just pathlib.Path.
Make zipfile.ZipInfo.compress_level public.
A property is used to retain the behavior of the ._compresslevel.
People constructing zipfile.ZipInfo instances to pass into existing APIs to control per-file compression levels already treat this as public, there was never a reason for it not to be.
I used the more modern name compress_level instead of compresslevel as the keyword argument on other ZipFile APIs is called to be consistent with compress_type and a general long term preference of not runningwordstogether without a separator in names.
Allow extraction (no-op) of a "/" folder in a zipfile, they are commonly added by some archive creation tools.

* Refactor zipfile._strip_extra to use higher level abstractions for extras instead of a heavy-state loop.
* Add blurb
* Remove _strip_extra and use _Extra.strip directly.
* Use memoryview to avoid unnecessary copies while splitting Extras.
Fix Zip64 extensions not being properly applied in some cases:
Fixes an issue where adding a small file to a `ZipFile`
object while forcing zip64 extensions causes an extra Zip64 record to be
added to the zip, but doesn't update the `min_version` or file sizes in
the primary central directory header.
Also fixed an edge case in checking if zip64 extensions are required:
This fixes an issue where if data requiring zip64 extensions was added
to an unseekable stream without specifying `force_zip64=True`, zip64
extensions would not be used and a RuntimeError would not be raised when
closing the file (even though the size would be known at that point).
This would result in successfully writing corrupt zip files.
Deciding if zip64 extensions are required outside of the `FileHeader`
function means that both `FileHeader` and `_ZipWriteFile` will always be
in sync. Previously, the `FileHeader` function could enable zip64
extensions without propagating that decision to the `_ZipWriteFile`
class, which would then not correctly write the data descriptor record
or check for errors on close.
If anyone is actually using `ZipInfo.FileHeader` as a public API without
explicitly passing True or False in for zip64, their own code may still be
susceptible to that kind of bug unless they make a similar change to
where the zip64 decision happens.

The zipfile.Path open() and read_text() encoding parameter can be supplied as a positional argument without causing a TypeError again. 3.10.0b1 included a regression that made it keyword only.
Documentation update included as users writing code to be compatible with a wide range of versions will need to consider this for some time.
This brings the Python implementation of `ntpath.normpath()` in line with the C implementation added in 99fcf15
