because fence->ctx is no longer always vrend_state.ctx0. It can also
point to a user context or be NULL now.

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.

A blob resource is a container for:
- VIRGL_RENDERER_BLOB_MEM_GUEST: a guest memory allocation
(referred to as a "guest-only blob resource")
- VIRGL_RENDERER_BLOB_MEM_HOST3D: a host3d memory allocation
(referred to as a "host-only blob resource")
- VIRGL_RENDERER_BLOB_MEM_HOST3D_GUEST: a guest + host3d memory allocation
(referred to as a "default blob resource").
Blob resources can be used to implement new features and fix shortcomings
with the current resource create path. The subsequent patches show how
blob resources may be leveraged to implement GL_ARB_buffer_storage
and GL4.5.
