Add a wrapper around the getfb2 ioctl, which returns extended
framebuffer information mirroring addfb2, including multiple planes and
modifiers.
Changes since v5:
- style change
Changes since v4:
- Set fb_id at init instead of memclear() and set (Eric Engestrom)
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
