peter mitrano 4514e4489a refactored HAL library
builds two libraries, Athena  and Desktop.
Simulation should use Desktop, Robots should use Athena

Also:
 - copied Driverstation and Joystick from Devices into Sim
 - Descreased dependency of pthreads in JNI.
 - removed Simulation ifdef from non simulation
 - added missing decprecated attribute for msvc
 - removed usage reporting from sim
 - removed unused pom.xml and constexpr
