cleanup: factor out SHelper typedef (and more)
It is totally useless to carry some data around in the SLifeData
global data, that is never used in a significant way. All data
in the SHelper typedef can trivially be changed to static
data in the new setAvgDepth code.
Further, cleanup the setAvgDepth code. Reset to 0 instead of 1,
adapt the references to the new local and static data instead
of pointers to the external data.
