Commit Message

Improve socket function replacement subsystem (#894)

Some external users swap out the entire IP stack, such as
[Seastar](https://github.com/scylladb/seastar) that uses DPDK. So we
need to allow them to override all network stack functions used by
c-ares. Since we don't know what network functions may be needed in the
future, we need to make a versioned structure that can be expanded.
We'll need to disable any features in the future if the versioned
interface is less than is required to support any new features.

We recently had a regression when we added DNS Cookie support as we
relied on `getsockname()` to get the local source ip address, but we
were calling the native version since there was no registered callback
available. We will mark this as optional and just skip this step in DNS
Cookie invalidation if its not available for the legacy api users.

Supersedes #893
