lib: instance ID's are now set to the process PID

All instance-id's in ouroboros will be set by the system to the pid of
the process associated with this application process instance. This
means that the user has no way to choose the instance id's. Function
calls that assumed manually defined instance id's have been replaced
throughout the system.
