bpo-37222: Fix for CacheFTPHandler in urllib
A call to FTP.ntransfercmd must be followed by FTP.voidresp to clear
the "end transfer" message. Without this, the client and server get
out of sync, which will result in an error if the FTP instance is
reused to open a second URL. This scenario occurs for even the most
basic usage of CacheFTPHandler.
Reverts the patch merged as a resolution to bpo-16270 and adds a test
case for the CacheFTPHandler in test_urllib2net.py.

This is the implementation of PEP683
Motivation:
The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime.
Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.
* bugfix: let the HTTP- and HTTPSHandlers respect the value of http.client.HTTPConnection.debuglevel
* add tests
* add news
* ReSTify NEWS and reword a bit.
* Address Review Comments.
* Use mock.patch.object instead of settting the module level value.
* Used test values to assert the debuglevel.

I recently added some tests to test_imp, but @warsaw is removing that file in gh-98573. The tests are worth keeping so here I'm moving them to test_import.
For example:
class Book(StrEnum):
title = auto()
author = auto()
desc = auto()
Book.author.desc is Book.desc
but
Book.author.title() == 'Author'
is commonly expected. Using upper-case member names avoids this confusion and possible performance impacts.

We no longer add a root to device paths such as `//./PhysicalDrive0`,
`//?/BootPartition` and `//./c:` while normalizing. We also avoid adding a
root to incomplete UNC share paths, like `//`, `//a` and `//a/`.

Improve performance of path construction by skipping the addition of the path anchor (`drive + root`) to the internal `_parts` list. Rename this attribute to `_tail` for clarity.
