Associations now keep track of the time they are actively involved in impacting their target application. This is based on the procstate propagating through the association being the same as the procstate of its target process... so it may count as active when there is another reason for that process to be in the same state. To do this, we now maintain a set of "tracking associations" -- these are in-use associations that we know we need to be tracking to determine whether they are active. This list is built based on whether we at all consider an association during an oom_adj computation, and at the end of that walked to determine which of those associations are currently active. Also add tracking of associations through external provider references, with a tag name now needing to be passed through so we can mark up the reason for the external reference.
