Add a wrapper around the getfb2 ioctl, which returns extended framebuffer information mirroring addfb2, including multiple planes and modifiers.
Changes since v3:
- remove unnecessary null check in drmModeFreeFB2 (Daniel Stone)
Changes since v2:
- getfb2 ioctl has been merged upstream
- sync include/drm/drm.h in a seperate patch
Changes since v1:
- functions should be drm_public
- modifier should be 64 bits
- update ioctl number

As mentioned on IRC, could you write it like this instead?
struct drm_mode_fb_cmd2 get = { .fb_id = fb_id, };
With that, consider this patch Reviewed-by: Eric Engestrom eric@engestrom.ch
Opps I sent v5 before seeing this but my code style differs and is probably incorrect :) I'll send v6 with the style corrected.
Thanks for reviewing!
