commit dc886bce753cc2cf3c88ec5c7a6880a4e17d65ba upstream.
Rename local_address() with "mptcp_" prefix and export it in protocol.h.
This function will be re-used in the common PM code (pm.c) in the
following commit.

[ Conflicts in pm_netlink.c and protocol.h, because the context has
changed in commit 4638de5aefe5 ("mptcp: handle local addrs announced
by userspace PMs") which is not in this version. This commit is
unrelated to this modification. Also some parts using 'local_address'
are not in this version, that's OK, we don't need to do anything with
them. ]
