gh-117566: fix IPv6Address.is_loopback for IPv4-mapped loopbacks (GH-117567)
While properties like IPv6Address.is_private account for IPv4-mapped
IPv6 addresses, such as for example:

    >>> ipaddress.ip_address("192.168.0.1").is_private
    True
    >>> ipaddress.ip_address("::ffff:192.168.0.1").is_private
    True
...the same doesn't currently apply to the is_loopback property:
    >>> ipaddress.ip_address("127.0.0.1").is_loopback
    True
    >>> ipaddress.ip_address("::ffff:127.0.0.1").is_loopback
    False

At minimum, this inconsistency between different properties is
counter-intuitive. Moreover, ::ffff:127.0.0.0/104 is for all intents and
purposes a loopback address, and should be treated as such.

GH-113171: Fix "private" (non-global) IP address ranges (GH-113179)
* GH-113171: Fix "private" (really non-global) IP address ranges

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.

I left 100.64.0.0/10 alone, for now, as it's been made special in [1]
and I'm not sure if we want to undo that as I don't quite understand the
motivation behind it.

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)
* GH-65056: Improve the IP address' is_global/is_private documentation

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).

gh-87799: Improve the textual representation of IPv4-mapped IPv6 addresses (#29345)
Represent IPv4-mapped IPv6 address as xxxd.d.d.d,
where the 'x's are the hexadecimal values
of the six high-order 16-bit pieces of the address,
and the 'd's are the decimal values
of the four low-order 8-bit pieces of the address
(standard IPv4 representation).

bpo-46415: Use f-string for ValueError in ipaddress.ip_{address,network,interface} helper functions (#30642)
`IPv*Network` and `IPv*Interface` constructors accept a 2-tuple of
(address description, netmask) as the address parameter.
When the tuple-based address is used errors are not propagated
correctly through the `ipaddress.ip_*` helper because of the %-formatting now expecting several arguments:

	In [7]: ipaddress.ip_network(("192.168.100.0", "fooo"))
        ...
	TypeError: not all arguments converted during string formatting

Compared to:

	In [8]: ipaddress.IPv4Network(("192.168.100.0", "foo"))
        ...
	NetmaskValueError: 'foo' is not a valid netmask

Use an f-string to make sure the error is always properly formatted.
