This program has been disabled for some time, but it's not
broken (even if the CMake was!).
Merging into the pcbnew_tools QA program reduces the CMake burden
and puts this tool in the same place as the others.
This means all the current Pcbnew utilities are all in a single
executable.
The tool is now run by:
$ qa/pcbnew_tools/qa_pcbnew_tools pcb_parser <same arguments as before>
Add a tool that allows a user to run DRC functions
on a given KiCad PCB file.
The first available functions are the courtyard functions.
Also move most of the utility program logic into qa_util for
better reusability.
