virgl/vtest: add vtest driver

virgl/vtest is a swrast driver that allows the
virgl acceleration to be tested without having
a virtual machine.

The backend has a unix socket server that
this connects to.

This is run by setting
LIBGL_ALWAYS_SOFTWARE=y
GALLIUM_DRIVER=virpipe

In this mode all renderering is sent over
a socket to the remote renderer, and the
results are readback and copies to the screen
using drisw. This works well enough to develop
new features and to help debug.

virgl: add driver for virtio-gpu 3D (v2)

virgl is the 3D acceleration backend for the
virtio-gpu shipping with qemu.

The 3D acceleration is designed around gallium
and TGSI as the virtualisation layer. The backend
renderer translates the virgl interface into
OpenGL currently.

This is the initial import of the driver to mesa.

The kernel driver portions are lined up for drm-next.

Currently this driver supports up to GL3.3 and some
misc extensions if the host driver exposes it. It is
planned to iterate the virgl API to new GL levels
as mesa host drivers gain features.

v2: fix resource tracking across flushes to avoid
->bind hack in mapping.
consolidate mapping and waiting code for transfers.
use u_range for dirt tracking.
handle larger shaders in protocol.
include virtgpu_drm.h in mesa for now.

In this case, all fragments will have the same color (unless blending is

This is a common case for OpenGL code such as: glColor(), glBegin(),
glVertex(), ..., glEnd() when lighting/fog/etc are disabled.  In this

execute the vertex shader to draw a point, then capture that point's
attributes.

But glRasterPos isn't typically used with a vertex shader so we can
usually use the old/fixed-function implementation which is a lot simpler
