graphics_overlay.cpp is based on a mix of AOSP code for graphics_fbdev.cpp along with overlay graphics code from CAF that was brought into earlier versions of TWRP and then further adapted and improved before being brought into this patch set. Also added a rule to build a minuitest binary for testing the minui engine to ensure proper operation on a device. Change-Id: I3972d3a6baa7002615319421ac07d9299c3cec69
