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.

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

…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.

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.
