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.
Move into own include directory for clarity. Also allows qa_utils
to use its own private headers in qa/qa_utils without exposing them
through the target_include_directories directive.
