when there is no current frame and _PyInterpreterState_IsRunningMain() returns
true.  This allows those functions to be run with Interpreter.call().

* gh-67022: Document bytes/str inconsistency in email.header.decode_header()

This function's possible return types have been surprising and error-prone
for the entirety of its Python 3.x history. It can return either:

1. `typing.List[typing.Tuple[bytes, typing.Optional[str]]]` of length >1
2. or `typing.List[typing.Tuple[str, None]]`, of length exactly 1

This means that any user of this function must be prepared to accept either
`bytes` or `str` for the first member of the 2-tuples it returns, which is a
very surprising behavior in Python 3.x, particularly given that the second
member of the tuple is supposed to represent the charset/encoding of the
first member.

This patch documents the behavior of this function, and adds test cases
to demonstrate it.

As discussed in bpo-22833, this cannot be changed in a backwards-compatible
way, and some users of this function depend precisely on the existing
behavior.

Add warnings about obsolescence of 'email.header.decode_header' and 'email.header.make_header' functions.

Recommend use of `email.headerregistry.HeaderRegistry` instead, as suggested
in https://github.com/python/cpython/pull/92900#discussion_r1112472177
