Make handling of dev_priv->vblank_pipe more robust.
...
Initialize it to default value if it hasn't been set by the X server yet.
In i915_vblank_pipe_set(), only update dev_priv->vblank_pipe and call
i915_enable_interrupt() if the argument passed from userspace is valid to avoid
corrupting dev_priv->vblank_pipe on invalid arguments.

DRM_I915_VBLANK_SWAP ioctl: Take drm_vblank_seq_type_t instead of pipe number.
...
Handle relative as well as absolute target sequence numbers.
Return error if target sequence has already passed, so userspace can deal with
this situation as it sees fit.
On success, return the sequence number of the vertical blank when the buffer
swap is expected to take place.
Also add DRM_IOCTL_I915_VBLANK_SWAP definition for userspace code that may want
to use ioctl() instead of drmCommandWriteRead().

i915: Add ioctl for scheduling buffer swaps at vertical blanks.

Actually make the existing ioctls for adding and removing drawables do

information. The only kind of drawable information tracked so far is cliprects.

Add support for secondary vertical blank interrupt to i915 driver.
...
When the vertical blank interrupt is enabled for both pipes, pipe A is
considered primary and pipe B secondary. When it's only enabled for one pipe,
it's always considered primary for backwards compatibility.
