This is a copy of the generic-tracing plugin for CoRedOS with the following
additions:
- random generator plugin is added if a "random_source" symbol is found
- checkpoint plugin is added if a "fail_trace" symbol is found. If stack
limits are defined by "_sstack" and "_estack" symbols this memory region
is checksummed on each checkpoint.
