[PATCH] migrate: Rename v1 address functions to v2 for clarity

[Jon Maloy <jmaloy@redhat.com>]

Some migration address structures and functions have a _v1 suffix.
This is confusing, since they are currently handling version 2 of
the migration protocol. We are soon going to introduce a new version
3 of the protocol, so we choose to give these functions the correct
suffix _v2 instead. This is in correspondence with current reality,
and will help make a clearer distinction between the old and the new
versions of those functions.
