We probably need another C file for this functionality but I agree the
objdb_track_start() api is the way to do it and it sounds like a great
feature.

I'd recommend putting the registration of callbacks and the handling of
them in a file such as logcfg.c and link that into the corosync binary.

If APIs are missing from logsys to do what you need feel free to send
patches on top of the logsys v2 tree.
