We're trying to introduce support for writeback connectors, a way to
expose in DRM the hardware functionality from display engines that
allows to write back into memory the result of the DE's composition
of supported planes.

Changelog:
 - This is basically a v3 of the i-g-t tests, except I've now dropped
   all the changes that were trying to split the CRC functionality out
   of lib/igt_debugfs.c. v2 is here:
   https://lists.freedesktop.org/archives/intel-gfx/2017-July/133154.html
 - Added meson support for builting the kms_writeback test
