A few changes to stated:
- fix bad indenting to a uniform 4 spaces (before was 2, 4 and 8 mixed) - Move ping-for-isup functionality into a separate script - Make sure every transition triggered by stated (directly or indirectly) sends an event, instead of taking shortcuts. This called for a new script, eventping, which just pings until the node is pingable, then sends an ISUP event. Stated runs this in the background where necessary, and nothing else should run it. Adding eventping meant modifying configure and the utils makefile, too.
