Being an interface of virgl_context, this provides per-context fencing.
This is motivated by Vulkan, where each context (i.e., VkInstance) is
independent from one another. Fences submitted to difference contexts
do not signal in the order they are submitted. It is in theory and in
practice also true for OpenGL when SW/HW scheduling or context priority
is considered.
Besides being per-context, fences in Vulkan are also per-VkDevice and
per-VkQueue within a context. This interface uses an opaque uint64_t to
identify the queue a fence is submitted to, similar to how an opaque
uint64_t is used to identify a blob.

There are two calls of do_readpixels, and both of them creates a new
frame buffer object and destroys it immediately after that. This change
integrates those operations into do_readpixels.
One thing to note that glReadBuffer(GL_COLOR_ATTACHMENT0) has been
called after binding such a newly created frame buffer object and before
calling do_readpixels in vrend_transfer_send_readpixels. The call is
simply deleted because a new frame buffer object should have
GL_COLOR_ATTACHMENT0 as read buffer.

vrend resource could cache a frame buffer object to read a texture
back. However, vrend resource is independent of OpenGL context
while a frame buffer object is not because it is a container
object. On QEMU, a frame buffer object is typically cached on each
renderer context while its destruction operation is performed on
"0 context", resulting in destroying another frame buffer object
whose name is identical but is created in "0 context".
This change simply removes the caching mechanism and eliminates the
need of a context switch when destroying a cached frame buffer
object and some handling of cache misses.

When we want to pass sub contexts directly to the function to avoid
