Add initial support for reusing the Mesa CI infrastructure.
Note this doesn't conflict with the old CI since it doesn't share the
'ci/' folder, but instead uses '.gitlab-ci/', which makes the new setup
consistent with Mesa CI.

because the contents of the structure can change even though the pointer

This is a fix for segfault issue, because of usage of uninitialized
vkQueue handle.
Spec [1] states that vkGetDeviceQueue must only be used to get queues
that were created with the flags parameter of VkDeviceQueueCreateInfo
set to zero. To get queues that were created with a non-zero flags
parameter use vkGetDeviceQueue2.
The problem that in case queue was created with flags set to zero following
vkGetDeviceQueue2 call will fail. By failing I mean that pQueue set to NULL,
which later leads to segfault.
This problem was also reported by vulkan validation layer:
vkr: vkGetDeviceQueue2: value of pQueueInfo->flags must not be 0. The Vulkan
spec states: flags must not be 0

When the flag is set, a render server is started and each vkr context is
replaced by a proxy context.
It does not apply to vrend contexts. There is no plan to support vrend
contexts either currently.
This also extends virgl_renderer_callbacks with a new callback. The
idea is to allow the client to start the render server externally. It
can be used to sandbox the render server, or is required when the client
process is sandboxed and cannot fork/exec/socketpair.

The render server is a daemon that sits idle waiting for commands. When
requested to create a context, it forks and creates the context in a
subprocess. This isolates contexts from each other, from the server
process, and from the client process.
Because a context process can execute untrusted commands and depends on
GPU drivers, the isolation should improve the security.
There is also a multi-thread mode where each context is executed by a
thread. This mode is used to ease debugging, but maybe someone will
find a use case for it.

This is similar to virgl_renderer_resource_import_eglimage, but is more
