Running Paparazzi on small hardware

Added some code that reduces the total binary size and thereby allows you to run the Paparazzi autopilot software on standard quadcopter hardware like the Naze32. It needs some documentation and example files that will be added to the Wiki once the weather gets better to fly. It even runs on the tiny CJMCU platform. Unfortunately you have to replace the original 64kByte flash processor (F103C8T6) with a 128kByte type (F103CBT6).
