…H-17773)

This uses the heuristic of assuming a named tuple is a subclass of
tuple with a _fields attribute. This change means that contents of
a named tuple wouldn't be converted - if a user wants to have
ConvertingTuple functionality from a namedtuple, they will have to
implement it themselves.

Mitigate performance regression of the list comparison caused by 2d5bf56.

…t_RichCompareBool (GH-17734)

Take strong references before calling PyObject_RichCompareBool to protect against the case
where the object dies during the call.

Tag memoryview, range, and tuple as classes, the same as list, etcetera, in
the library manual built-in functions list.

Hold strong references to list elements while calling PyObject_RichCompareBool().

The importlib.metadata documentation uses hardcoded links to internal
pages. This results in minor rendering issues. This change replaces
the hardcoded links with suitable Sphinx roles.

…e Python stdlib files (GH-17721)

The comment about the collection rules for the permanent generation was
incorrectly referenced by a comment in gcmodule.c (the comment has been
moved long ago into a header file). Moving the comment into the relevant
code helps with readability and avoids broken references.

`time.clock()` was removed in Python 3.8, but it was still mentioned
in the documentation for when `time.get_clock_info()` is given the
argument `'clock'`. This commit removes that mention.

…H-7917) (GH-17677)

A character "i" is omitted.

Small typo/formatting corrections.
`whethen` -> `whether` 
`exaustion' -> `exhaustion`
Assorted appending periods `.` and slight reformattings to place `Path contributed by` on the same line as description, matching the majority of document.

NB Some of these might need to be backported, as I saw the first error in the [changelog for 3.8.1](https://docs.python.org/3.8/whatsnew/changelog.html#python-3-8-1)

The added parentheses around the PyIter_Next assignment suppress the following warning which gcc throws without:
```
warning: using the result of an assignment as a condition without parentheses [-Wparentheses]
```
The other change is a typo fix
