Virglrenderer sometimes tries to remove resources from the hash table
twice. Which will mess up the ressource hash table and reference counts
and therefore and leads to qemu/virglrenderer crashes.
Reproducer:
(a) guest creates resource foo, id 42.
(b) guest creates an object bar referencing resource foo.
(c) guest unreferences resource foo.
-> resource id 42 is removed from hash.
(d) guest creates a new resource baz, re-using id 42.
(e) guest destroys object bar.
-> resource foo refcount goes down to zero.
-> resource id 42 gets removed from hash the second time,
but id 42 entry points to resource baz not foo now.
Oops.
Note that most linux kernel drivers will never ever re-use resource ids
due to a bug in the virtio-gpu kms driver, in which case this bug
doesn't cause any harm.
Root cause is that vrend_renderer_resource_destroy() may call
vrend_resource_remove(), depending on the call chain. This is wrong.
Only vrend_renderer_resource_unref() which is called when the guest
unreferences a resource should remove the id from the hash table by
calling vrend_resource_remove().

mesa optimizes away the information about input layouts for generics and

When calling vrend_renderer_transfer_write_iov through
vrend_renderer_transfer_iov, we sometimes come down these
code-paths with the context 0 active, but the non-zero context being
passed as the context-pointer. Trying to do any caching based on this
will only lead to incorrect behavior.
There's little point in trying to fixup the caching in the ctx0 for
this call-site, as there's no other code-path using ctx0 that tries
to play ball with the cache.
So let's get rid ot the context-argument when possible, and pass a
NULL-pointer when it can come either from ctx0 or a rendering-context.

v2: Instead of releasing the UBO's at the end don't reference count them.
The guest keeps track of these resources and their reference counts,
so it will not release the UBO's without re-setting the binding during
the live time of a client progra, However, at final clean up the UBO's
are not rebound before the resourse is released in the guest side resulting
in the memory leak. When we skip the ref-counting on the host side the
resourses are cleaned up correctly without breaking the program otherwise.
