Make sure that the passed buffer size is not negative and that
evaluating the buffer size in bytes doesn't overflow. With that
we make sure that the buf_offset in the decoding loop can't wrap
around when it is updated.

- remove the size conversion on both ends
v3: - keep conversion to size in bytes (Chia-I)

Per-context fences signal in creation order only within a context. Two
per-context fences in two contexts might signal in any order.
When a per-context fence is created, a fence cookie can be specified.
The cookie will be passed to write_context_fence callback. This
replaces fence_id that is used in ctx0 fencing.
write_context_fence is called on each fence unless the fence has
VIRGL_RENDERER_FENCE_FLAG_MERGEABLE set. When the bit is set,
write_context_fence might be skipped.

Other than hooking things up, vrend_renderer_check_fences and
vrend_renderer_export_ctx0_fence have some non-trivial changes. This is
because fence->ctx is no longer always vrend_state.ctx0. It can also
point to a user context or be NULL now.

A fence cookie (void *) is more flexible than a fence id to the users.
When per-context fencing is introduced, its API will use fence cookies.
Conversions between fence ids and fence cookies are some free casts.

Replace the unused ctx_id by a vrend_context pointer. When a
vrend_context is destroyed, remove fences associated with the context to
avoid dangling pointers.
For now, the context is always ctx0 which is never destroyed before the
fences. That will change later when per-context fencing is introduced.

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.
