Fix a crash caused by immortal interned strings being shared between
sub-interpreters that use basic single-phase init. In that case, the string
can be used by an interpreter that outlives the interpreter that created and
interned it. For interpreters that share obmalloc state, also share the
interned dict with the main interpreter.
This is an un-revert of gh-124646 that then addresses the Py_TRACE_REFS
failures identified by gh-124785 (i.e. backporting gh-125709 too).

* gh-121650: Encode newlines in headers, and verify headers are sound (GH-122233)
- Encode header parts that contain newlines
Per RFC 2047:
> [...] these encoding schemes allow the
> encoding of arbitrary octet values, mail readers that implement this
> decoding should also ensure that display of the decoded data on the
> recipient's terminal will not cause unwanted side-effects
It seems that the "quoted-word" scheme is a valid way to include
a newline character in a header value, just like we already allow
undecodable bytes or control characters.
They do need to be properly quoted when serialized to text, though.
- Verify that email headers are well-formed
This should fail for custom fold() implementations that aren't careful
about newlines.

* GH-113171: Fix "private" (non-global) IP address ranges (GH-113179)
The _private_networks variables, used by various is_private
implementations, were missing some ranges and at the same time had
overly strict ranges (where there are more specific ranges considered
globally reachable by the IANA registries).
This patch updates the ranges with what was missing or otherwise
incorrect.
100.64.0.0/10 is left alone, for now, as it's been made special in [1].
The _address_exclude_many() call returns 8 networks for IPv4, 121
networks for IPv6.

* GH-65056: Improve the IP address' is_global/is_private documentation (GH-113186)
It wasn't clear what the semantics of is_global/is_private are and, when
one gets to the bottom of it, it's not quite so simple (hence the
exceptions listed).
