Timeout stalled transfers and cleanup related data structures. Default
to wait five minutes since last update. Hook onto registration/ping message
type to trigger cleanup in a minimally invasive manner.

While here restructure certain functions to use list_* functions

Otherwise --mail-type=ALL will send an unexpected stage_out message back
to the user.

Make default compression vary based on library availability.

A node's CPULoad was getting reset to NoVal on reconfiguration.
This change preserves the old value, which can fix a possible
