Add a base class that is common to virtio-gpu and vhost-user-gpu
devices.
The VirtIOGPUBase base class provides common functionalities necessary
for both virtio-gpu and vhost-user-gpu:
- common configuration (max-outputs, initial resolution, flags)
- virtio device initialization, including queue setup
- device pre-conditions checks (iommu)
- migration blocker
- virtio device callbacks
- hooking up to qemu display subsystem
- a few common helper functions to reset the device, retrieve display
informations
- a class callback to unblock the rendering (for GL updates)
What is left to the virtio-gpu subdevice to take care of, in short,
are all the virtio queues handling, command processing and migration.

Add a new vhost-user message to give a unix socket to a vhost-user
backend for GPU display updates.
Back when I started that work, I added a new GPU channel because the
vhost-user protocol wasn't bidirectional. Since then, there is a
vhost-user-slave channel for the slave to send requests to the master.
We could extend it with GPU messages. However, the GPU protocol is
quite orthogonal to vhost-user, thus I chose to have a new dedicated
channel.
See vhost-user-gpu.rst for the protocol details.

We mandate that the source node must be a root node; but there's no reason
I am aware of that it needs to be restricted to such. In some cases, we need
to make sure that there's a medium present, but in the general case we can
allow the backup job itself to do the graph checking.
This patch helps improve the error message when you try to backup from
the same node more than once, which is reflected in the change to test
056.
For backups with bitmaps, it will also show a better error message that
the bitmap is in use instead of giving you something cryptic like "need
a root node."

Valgrind detects multiple issues in QEMU iotests when the memory is

that is true for the aligned bitmap directory and can be seen while

In the following case:
(base) A <- B <- C (tip)
when running:
qemu-img rebase -b A C
QEMU would read all sectors not allocated in the file being rebased (C)
and compare them to the new base image (A), regardless of whether they
were changed or even allocated anywhere along the chain between the new
base and the top image (B). This causes many unneeded reads when
rebasing an image which represents a small diff of a large disk, as it
would read most of the disk's sectors.
Instead, use bdrv_is_allocated_above() to reduce the number of
unnecessary reads.

A consequence of the previous patch is that bdrv_attach_child()
transfers the reference to child_bs from the caller to parent_bs,
which will drop it on bdrv_close() or when someone calls
bdrv_unref_child().
But this only happens when bdrv_attach_child() succeeds. If it fails
then the caller is responsible for dropping the reference to child_bs.
This patch makes bdrv_attach_child() take the reference also when
there is an error, freeing the caller for having to do it.
A similar situation happens with bdrv_root_attach_child(), so the
changes on this patch affect both functions.

[mreitz: Removed now superfluous BdrvChild * variable in
bdrv_open_child()]
Signed-off-by: Max Reitz <mreitz@redhat.com>
bdrv_unref_child() does the following things:
- Updates the child->bs->inherits_from pointer.
- Calls bdrv_detach_child() to remove the BdrvChild from bs->children.
- Calls bdrv_unref() to unref the child BlockDriverState.
When bdrv_unref_child() was introduced in commit 33a604075c it was not
used in bdrv_close() because the drivers that had additional children
(like quorum or blkverify) had already called bdrv_unref() on their
children during their own close functions.
This was changed later (in 0bd6e91a7e for quorum, in 3e586be0b2 for
blkverify) so there's no reason not to use bdrv_unref_child() in
bdrv_close() anymore.
After this there's also no need to remove bs->backing and bs->file
separately from the rest of the children, so bdrv_close() can be
simplified.
Now bdrv_close() unrefs all children (before this patch it was only
bs->file and bs->backing). As a result, none of the callers of
brvd_attach_child() should remove their reference to child_bs (because
this function effectively steals that reference). This patch updates a
couple of tests that were doing their own bdrv_unref().

This tag contains a handful of patches that I'd like to target for 4.1:
* An emulation for SiFive's GPIO device.
* A fix to disallow sfence.vma from userspace.
* Additional decodetree cleanups that should have no functional impact.
* C extension emulation fidelity fixes that were noticed as part of that
cleanup process.
* A new "spike" target, along with the deprecation of a handful of old
targets and CPUs.
* Some initial infastructure related to the hypervisor extension.
* An emulation fidelity fix that prevents prevents arbitrary bits in the
SIP CSR from being set.
* A small performance improvement that avoids excessive TLB flushing
when the ASID does not change.
This time I've used a new testing workflow: I've tested on both 32-bit
and 64-bit builds of OpenEmbedded, via the default OpenSBI-based boot
flow.
