This means that utility programs no longer have to be manually
added to the COMBINED_UTILITY, they self-register their
information at static init time. This is basically the same concept
as the Boost test registration.
All utilities need to do now is register their UTILITY_PROGRAM info
struct with the UTILITY_REGISTRY::Register method. No headers required.
SCOPED_TIMER is a QA-only simpler version of PROF_COUNTER.
Extend PROF_COUNTER to allow access to the std::chrono::duration
for more flexibility.
Wrap PROF_COUNTER in SCOPED_PROF_COUNTER for RAII duration
output (for the same effect as SCOPED_TIMER).
This allows to feed any data directly into the sexpr parser. This can be
used for:
* Benchmarking, profiling and optimisation
* Fuzz testing
* Debugging
As an example, it demonstrates that a 15MB kicad PCB file (the CIAA
motherboard project) takes 1.5s to parse, and uses 140MB of heap
allocation within the Parse() method (using Valgrind massif).
