drm/nouveau: new gem pushbuf interface, bump to 0.0.16
This commit breaks the userspace interface, and requires a new libdrm for nouveau to operate again. The multiple GEM_PUSHBUF ioctls that were present in 0.0.15 for compatibility purposes are now gone, and replaced with the new ioctl which allows for multiple push buffers to be submitted (necessary for hw index buffers in the nv50 3d driver) and relocations to be applied on any buffer. A number of other ioctls (CARD_INIT, GEM_PIN, GEM_UNPIN) that were needed for userspace modesetting have also been removed.
