e4fa8457b2 drm/prime: Align gem_prime_export with obj_funcs.export 
The idea is that gem_prime_export is deprecated in favor of
obj_funcs.export. That's much easier to do if both have matching
function signatures.

b283e92a23 drm/prime: Shuffle functions. 
Reorder all the functions in drm_prime.[hc] into three groups: core,
export helpers, import helpers.

Not other changes beyond moving the functions and their unchanged
kerneldoc around in here.

3ed4351a83 drm: Extract drm_vblank.[hc] 
drm_irq.c contains both the irq helper library (optional) and the
vblank support (optional, but part of the modeset uapi, and doesn't
require the use of the irq helpers at all.

Split this up for more clarity of the scope of the individual bits.

v2: Move misplaced hunks to this patch (Stefan).

7e491583df drm/prime: Introduce drm_gem_prime_import_dev 
The existing drm_gem_prime_import function uses the underlying
struct device of a drm_device for attaching to a dma_buf. Some drivers
(notably vgem) may not have an underlying device structure. Offer
an alternate function to attach using any available device structure.

a8f8b1d9b8 drm: Extract drm_file.h 
I'm torn on whether drm_minor really should be here or somewhere else.
Maybe with more clarity after untangling drmP.h more this is easier to
decide, for now I've put a FIXME comment right next to it. Right now
we need struct drm_minor for the inline drm_file type helpers, and so
it does kinda make sense to have them here.

Next patch will kerneldoc-ify the entire pile.
