drm: Add GEM ("graphics execution manager") to i915 driver.
GEM allows the creation of persistent buffer objects accessible by the graphics device through new ioctls for managing execution of commands on the device. The userland API is almost entirely driver-specific to ensure that any driver building on this model can easily map the interface to individual driver requirements. GEM is used by the 2d driver for managing its internal state allocations and will be used for pixmap storage to reduce memory consumption and enable zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.
