Try to hit a bug in the kernel whereby a short reader does not wakeup
the next waiter (on the same fd) leading to forever blocking.

Simple rule of thumb, if a kms_* test calls igt_display_init() in its
global fixture, skip the entire test if the driver has disabled KMS.

The first active pipe might not be pipe A, and we shouldn't rely on
fbcon for a working crtc. Use igt_kms to set up something basic, and
use the kmstest helper to get an event from the correct pipe.

So the test runs on other drivers, drop the usage of the i915-specific
DRM_IOCTL_I915_GET_PIPE_FROM_CRTC_ID ioctl.
Wait for a vblank event on pipe0 and if we get it, then the test can
proceed (code copied from kms_vblank).

For those tests that now pass on drivers other than i915, call
drm_open_driver_master with DRIVER_ANY.
Also do so from igt_enable_connectors.

In order to test drivers that don't have support for proper buffer
objects, add a wrapper for creating dumb buffer objects that will be
called from the lib code for those subtests that don't need to care.

Ensure that O_NONBLOCK isn't accidentally set when we want a nonblocking
file descroptor.

In theory, this should force i915_gem_fault() when we first use the
buffer (and not at mmap time) and so prevent a __copy_to_user_inatomic()
from writting to the buffer.

Add a header that includes all the headers for the library. This allows
reorganisation of the library without affecting programs using it and
also simplifies the headers that need to be included to use the library.

As we require a pipe enabled to generate vblanks, the first step is to
then to check that pipe 0 is active or else skip the test.

Check that the more obvious userspace error conditions are handled by
the kernel, ideally without loss of data. These include nonblocking
waits, passing invalid buffers and passing buffers of the incorrect
length.
