[PATCH 3/4] drm: add libdrm_amdgpu (v3)

This is the new ioctl wrapper used by the new admgpu driver. It's primarily used by xf86-video-amdgpu and mesa.

v2: fix amdgpu_drm.h install v3: Integrate some of the sugestions from Emil: clean up Makefile.am, configure.ac capitalize header guards fix _FILE_OFFSET_BITS with config.h use drm_mmap/drm_munmap Remove unused ARRAY_SIZE macro use shared list implementation use shared math implementation use drmGetNodeTypeFromFd helper
