* Renames /qa/common to /qa/qa_utils, as it is not to do with /common
* Renames /qa/geometry to /qa/common
* Put existing geometry tests into a subdirectory of /qa/common, to
echo the layout of the main tree.
The intention is to provide a place to put tests of other libcommon
code in the /qa/common suite.
This commit finishes the removal of OpenMP from the KiCad codebase.
Removed in this commit are the OpenMP calls in 3d-viewer and
qa/polygon_triangulation as well as all references in CMakeLists.txt
std::thread is used instead for multithreaded computation
OpenMP is not available for macos, so moving to a std::threads
implementation brings platforms into shared code.
This also reduces the OpenMP overhead when computing connectivity and
ratsnests.
