Auto merge of #75019 - nanpuyue:to_ipv4_mapped, r=LukasKalbertodt
Add Ipv6Addr::to_ipv4_mapped * add Ipv6Addr::to_ipv4_mapped * ~~deprecate Ipv4Addr::to_ipv6_compatible & Ipv6Addr::to_ipv4~~ reference: #75150 According to [IETF RFC 4291](https://tools.ietf.org/html/rfc4291#page-10), the "IPv4-Compatible IPv6 address" is deprecated. > 2.5.5.1. IPv4-Compatible IPv6 Address > > The "IPv4-Compatible IPv6 address" was defined to assist in the IPv6 > transition. The format of the "IPv4-Compatible IPv6 address" is as > follows: > > | 80 bits | 16 | 32 bits | > +--------------------------------------+--------------------------+ > |0000..............................0000|0000| IPv4 address | > +--------------------------------------+----+---------------------+ > > Note: The IPv4 address used in the "IPv4-Compatible IPv6 address" > must be a globally-unique IPv4 unicast address. > > The "IPv4-Compatible IPv6 address" is now deprecated because the > current IPv6 transition mechanisms no longer use these addresses. > New or updated implementations are not required to support this > address type. And the current implementation of `Ipv4Addr::to_ipv6_compatible`is incorrect: it does not check whether the IPv4 address is a globally-unique IPv4 unicast address. Please let me know if there are any issues with this pull request.
