This exercises both the wc mmappings and the extended get_tiling ioctl.
Userspace cannot handle bit17 swizzling through wc mmaps (because bit17
requires swizzling based on the actual physical address of the page -
which is unknown to userspace) and so we need an extended get_tiling
ioctl to report the actual as well as the logical swizzling on an
object. We then check that the contents of the object are tiled and
swizzled correctly when viewed through a wc mmap.

Add a test to verify that pwriting to a future scanout buffer works
correctly. The specific problem occurs when the buffer is already
UC/WT before the pwrite, not the current scanout buffer, and not
currently in the CPU write domain. With the buggy kernel no clflush
will be performed after the pwrite, and hence we end up with cache
dirt on the display.
The problem only affects LLC platforms (non-LLC would clflush anyway
after pwrite), but we can let the test run on all platforms.

Add a simple test to exercise universal plane support.
v6:
- Update to new universal plane interface (commit parameter rather than
state-changing function). It should now be a lot more explicit which
steps are being taken with legacy API's vs universal API's now.
v5:
- Check that we don't have more than one primary or cursor. This will
catch accidental calls to drm_plane_init() in the kernel where
drm_universal_plane_init() was intended (these don't cause a compile
warning due to type compatibility between enum and bool).
v4:
- Test disabling the primary plane explicitly when it has previously
been implicitly disabled due to clipping.
- Skip test if igt_pipe_crc_new() fails
v3:
- For testing while crtc is off, switch between several different
primary plane fb's before reenabling the crtc. This will help
catch pin/unpin mistakes.
v2:
- Test that pageflips error out gracefully when the primary plane
is disabled before the ioctl, or between ioctl and pageflip
execution.
- Test that nothing blows up if we try to disable the primary plane
immediately after a pageflip (presumably before the pageflip actually
completes).
- Test that we can setup primary + sprite planes with the CRTC off and
then have them show up properly when we enable the CRTC
(drmModeSetCrtc with fb = -1).
- Test that we can modeset properly after having disabled the primary
plane
- Test that proper error codes are returned for invalid plane
programming attempts.

A set of userptr test cases to support the new feature.
For the eviction and swapping stress testing I have extracted
some common behaviour from gem_evict_everything and made both
test cases use it to avoid duplicating the code.
Both unsynchronized and synchronized userptr objects are
tested but the latter set of tests will be skipped if kernel
is compiled without MMU_NOTIFIERS.
Also, with 32-bit userspace swapping tests are skipped if
the system has a lot more RAM than process address space.
Forking swapping tests are not skipped since they can still
trigger swapping by cumulative effect.
v2:
* Fixed dmabuf test.
* Added test for rejecting read-only.
* Fixed ioctl detection for latest kernel patch.
v3:
* Use ALIGN macro.
* Catchup with big lib/ reorganization.
* Fixed up some warnings.

The Broadwell GT3 machine has two independent BSD rings in kernel driver while
it is transparent to the user-space driver. In such case it needs to check
the ring sync between the two BSD rings. At the same time it also needs to
check the sync among the second BSD ring and the other rings.

Thomas noticed that in simulation mode a lot of the tests fall over
instead of skipping properly. This is due to recently added
self-checks which ensure that any call to igt_skip happens either
within a fixture or subtest block (or it's a simple test without
subtests). This is to catch bugs since pretty much always not wrapping
up hardware setup and checks into these blocks is a bug.
Bug simulation skipping is a bit different, so allow that exception.
Otherwise we'd need to fix up piles of tests (and likely need to play
a game of whack-a-mole).
Also add a library testcase for all the different variants to make
sure it really works.
