Christian Dietrich c24ed774b0 experiments/dciao-kernelstructs: new database driven experiment for DCiAO
The dciao-kernelstructs experiment does a trace imported by the
DCiAOKernelImporter:

   bin/import-trace -t trace.pb  -i DCiAOKernelImporter --elf-file app.elf

Pruned by the basic method:

   bin/prune-trace

and does CiAO fault injection experiments, where the results are
stored in the database.
