Rename the existing reuseport helpers for IPv4 and IPv6 so that they
can be invoked in the follow up commit. Export them so that DCCP which
may be built as a module can access them.
We need not export the functions unless there is a real user.
I added a deprecation notice for DCCP recently, so I bet DCCP
will not get SO_REUSEPORT support.

Misleading commit message, it turns out that ipv6 as a module also
needs (the v6 functions at least) to be EXPORT_SYMBOL'd. That's
because of some special shenanigans where inet6_hashtables.c is linked
into vmlinux even when CONFIG_IPV6=m.
Also not sure how to work around this: DCCP may be deprecated but
without the export a module build of it fails.
If it breaks the build, then we need to export it.
