Here's the latest iteration of the universal planes work, which I believe is
finally ready for merging.  Aside from the minor driver patches to use the
new drm_for_each_legacy_plane() macro for plane loops, these should all have
an r-b from Rob Clark now.

Actual userspace-visibility is currently hidden behind a
drm.universal_planes module parameter so that we can do some experimental
testing of this before flipping it on universally.

    drm/i915: don't disable disconnected outputs

This was originally introduced to make encoder sharing on radone
easier for userspace, but:

- It is policy and as such belongs into userspace. E.g. personally I'm
  fairly annoyed that a flaky cable results in permanent changes of
  the desktop layout, so I'll kick out DEs which do this. Worse if the
  kernel also tries to be clever.

- It's inconsistent: We only kill disconnected outputs on setCrtc
  (which userspace might also call when just changing the
  framebuffer), but not when e.g. we receive a hpd event or in the
  output poll worker.

- It's unexpected behaviour for the userspace driver, at least in the
  intel ddx we've had tons of bugs where the driver fell over and
  killed the X session becuase pageflips/vblanks suddenly stopped
  working. We've had to fix this by wrapping every single setCrtc int
  a big "recover kms state from the kernel again" operation.

- It's suprising for the kernel, too: It took a few mails between Rob,
  Matt and me for them to notice that little dragon wreaking havoc
  with the universal plane framebuffer refcounting.

- Userspace can cope with it and e.g. Gnome already kills disconnected
  outputs and reconfigures the desktop automatically. And since there
  have been no regression reports for the i915 change from over 1 year
  ago I think all other DEs are also ready.

Earlier this week, there was a bit of confusion about those new
capabilities, to the point I think it's better to document the intention
and API contract.

The comment documents the current situation:
 - the radeon driver returns the only valid size for the hw
 - i915 returns the maximun cursor size
 - other drivers fall back to returning 64x64

The common contract is to return a valid cursor size.

When we expose non-overlay planes to userspace, they will become
accessible via standard userspace plane API's.  We should be able to
handle the standard plane operations against primary planes in a generic
way via the modeset handler.

Drivers that can program primary planes more efficiently, that want to
use their own primary plane structure to track additional information,
or that don't have the limitations assumed by the helpers are free to
provide their own implementation of some or all of these handlers.

v3: Tweak kerneldoc formatting slightly to avoid ugliness
v2:
 - Move plane helpers to a new file (drm_plane_helper.c)
 - Tighten checks on update handler (check for scaling, CRTC coverage,
   subpixel positioning)
 - Pass proper panning parameters to modeset interface
 - Disallow disabling primary plane (and thus CRTC) if other planes are
   still active on the CRTC.
 - Use a minimal format list that should work on all hardware/drivers.
   Drivers may call this function with a more accurate plane list to
   enable additional formats they can support.
