Commit 6b5b013 ("bpo-26978: Implement pathlib.Path.link_to (Using
os.link) (pythonGH-12990)") introduced a new link_to method in pathlib. However,
this makes pathlib crash when the 'os' module is missing a 'link' method.

Fix this by checking for the presence of the 'link' method on pathlib
module import, and if it's not present, turn it into a runtime error like
those emitted when there is no lchmod() or symlink().

… *reuse_address* parameter (python#17595)

Each Python subinterpreter now has its own "small integer
singletons": numbers in [-5; 257] range.

It is no longer possible to change the number of small integers at
build time by overriding NSMALLNEGINTS and NSMALLPOSINTS macros:
macros should now be modified manually in pycore_pystate.h header
file.

For now, continue to share _PyLong_Zero and _PyLong_One singletons
between all subinterpreters.

All keywords should first be checked for pointer identity. Only
after that failed for all keywords (unlikely) should unicode
equality be used.
The original code would call unicode equality on any non-matching
keyword argument. Meaning calling it often e.g. when a function
has many kwargs but only the last one is provided.

Quick subclasshook fix using the same method is being used in collections.abc (up to a certain degree).

"HH", "MM" and "ffffff" are enclosed with double back quotes, but "SS" is left being bare

Fixes a nearly word for word duplication of a sentence that appears
earlier in the caution section of datetime.datetime.fromisoformat in
Doc/Library/datetime.rst.

No issue created as it's a trivial change.

When checking `setup.py` and when the `author` field was provided, but
the `author_email` field was missing, erroneously a warning message was
displayed that the `author_email` field is required.

The specs do not require the `author_email`field:
https://packaging.python.org/specifications/core-metadata/#author

The same is valid for `maintainer` and `maintainer_email`.

The warning message has been adjusted.

…ce regression on import (pythonGH-17376)" (pythonGH-17687)

This reverts commit ded8888.

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

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)

A character "i" is omitted.

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.

Remove extra space to fix formatting and avoid from splitting text in to strings.

When producing the bytecode of exception handlers with name binding (like `except Exception as e`) we need to produce a try-finally block to make sure that the name is deleted after the handler is executed to prevent cycles in the stack frame objects. The bytecode associated with this try-finally block does not have source lines associated and it was causing problems when the tracing functionality was running over it.
