commit b6cbb26e25e52440c01bf070c4630af1b37a50fb
Author: Jonathon Jongsma <jjongsma at redhat.com>

Replace a couple Rings with GList
Make RedsState::mig_target_clients into a GList to improve encapsulation
and maintainability. Also RedsMigTargetClient::pending_links. With
GList, a type implementation can be ignorant of whether they're
contained within a list or not.
