1. We can create resource with size of "1" on drm, because size
is not passed to the renderer.
2. We can't create resource with size of "1" on vtest, because shmem
is created based on that.
3. If renderer supports copy_transfer_from_host, then use staging
buffer for transfer in both ways to and from host.
This will allow to reduce memory consumption in the guest.
v2:
- add inline function for checking if we can use this optimization
- add check in readback path. If renderer doesn't support
copy transfer from host, then we need to go with previous
path in readback (through transfer_get ioctl)
v3:
- fix logic for readback
v4:
- refactor the implementation to integrate it more to
existing code base
v5:
- reuse COPY_TRANSFER3D in both directions
v6:
- encode direction in COPY_TRANSFER3D if host supports it
v7:
- renamed cap bit
- introduced COPY_TRANSFER3D_SIZE_LEGACY define

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.

Modern games may use more than 16 sampler views, so get what the host
actually supports, and default to 16 on old hosts that don't pass the
value.
Since the possible maximal value of PIPE_MAX_SHADER_SAMPLER_VIEWS doesn't
fit into an uint32_t remove the binding flags, they were only used for
releasing the sampler views, and this can be achieved differently.

Some game engines rely on the real hardware info to adjust default
graphics quality and other attributes.
Prepend "virgl" to avoid app compat issues and to distinguish from
native platforms while giving engines/apps a chance to adjust graphics
defaults.

This field was introduced 2 months ago and it breaks virgl
compatibility between guest/host. Switch the new added field
to the end. We will still have compatibility issue but the
"bug window" is much smaller.
