Extend virtual test driver (VKMS)
---------------------------------
See the documentation of :ref:`VKMS <vkms>` for more details. This is an ideal
internship task, since it only requires a virtual machine and can be sized to
fit the available time.

====
CRC API
-------
- Optimize CRC computation ``compute_crc()`` and plane blending ``blend()``
- Use the alpha value to blend vaddr_src with vaddr_dst instead of
overwriting it in ``blend()``.
- Add igt test to check cleared alpha value for XRGB plane format.
- Add igt test to check extreme alpha values i.e. fully opaque and fully
transparent (intermediate values are affected by hw-specific rounding modes).
