lib, tools: Rename application process and instance

This refactors ouroboros to use "program" instead of "application
process" and "process" instead of "application process instance" to
align with current naming in current Operating Systems courses instead
of the ISO nomenclature adopted by RINA. This change permeates through
the entire implementation. Also contains some minor other refactors.
