Christine Caulfield 55c3dcb76d stats: Add map with on-demand statistics 
Icmap is factored out so it's possible to add other
maps for cmap. API call to switch maps from application
end is added.

Corosync-cmapctl is enhanced with -m option.

Stats contains all statistics previously found in runtime.connections,
runtime.services and runtime.totem prefixes together with new knet
related. All stats are read only.
