Add a new command associated to glLinkProgram. With this we should be
able to compile and link shaders when requested by the user, thus
avoiding that to happen in the middle of a frame.
Together with the command we pass an array of shader handles attached to
the program, where each position of the array corresponds to a pipe
shader type.

the only case in which this is nonzero is if a multidraw gets split by the frontend,
i.e., mesa core, and in all other cases it can be ignored. the value can also be ignored
for all indirect draws, though it seems many (most?) gallium drivers are not aware of this

Essentially rename multi_draw to draw_vbo and remove start and count
from pipe_draw_info.
This is only an interface change. It doesn't add multi draw support
anywhere.

The virgl formats are fixed in time snapshots of the gallium ones,
we just need to provide a translation table between them when
we enter the hardware.
This fixes a regression since Eric renumbered the gallium table.

Support transfers that use a different resource as the source of data to
transfer. This will be used in upcoming commits to send data to host
buffers through a transfer upload buffer, in order to avoid waiting
when the buffer resource is busy.
Note that we don't support queueing copy transfers in the transfer
queue. Copy transfers should be emitted directly in the command queue,
allowing us to avoid flushes before them and leads to better
performance.

pipe_draw_info::indexed is replaced with index_size. index_size == 0 means
non-indexed.
Instead of pipe_index_buffer::offset, pipe_draw_info::start is used.
For indexed indirect draws, pipe_draw_info::start is added to the indirect
start. This is the only case when "start" affects indirect draws.
pipe_draw_info::index is a union. Use either index::resource or
index::user depending on the value of pipe_draw_info::has_user_indices.

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.
add translation layer for gallium tgsi to virgl tgsi.
