I recently had this discussion with Daniel where I didn't want to use
igt_drm_format_to_bpp() because it uses the format_desc array, and
igt_fb currently assumes that all the format_desc formats have a
matching valid Cairo format, so I wouldn't be able to easily add
formats such as ARGB2101010.
The function that has the assumption mentioned above is
igt_get_all_formats: its current users call igt_get_all_formats, and
then call cairo-dependent functions, such as igt_get_cairo_ctx on the
returned formats.
In order to document the current behavior and prevent any problems in
case we start adding new formats without matching Cairo versions to
format_desc, rename igt_get_all_formats to igt_get_all_cairo_formats
and make it explicitly check for CAIRO_FORMAT_INVALID.

Several tests do one or more of the following:
* igt_create_fb() + igt_paint_test_pattern()
* igt_create_color_fb() + igt_paint_test_pattern()
* igt_create_fb() + igt_paint_image()
Extract them into new helpers: igt_create_pattern_fb(),
igt_create_color_pattern_fb(), igt_create_image_fb().

Add tests for KMS atomic modesetting, to exercise the basic interface
and test failure/corner cases. Should ensure coherency between the
legacy and atomic interfaces.
v2: New patch.
v3: Disable connector checking for now, as it was causing GPU hangs on
newer kernels.
v4: Rebase.
v5: Use do_ioctl or do_ioctl_err consistently. Use igt_assert_*()
helper macros rather than igt_assert() directly.
Move assertions into helper/check functions. Define atomic commit
helper.
v6: Use do_ioctl_err, and define macros to move errors to
actual callsite, rather than helper functions.
