Create an i2c-bus interface, corresponding to the I2CAdapter struct.
Wrap IMXI2C and OMAPI2C with a QOSGraphObject, and add the get_driver
function to retrieve the I2CAdapter.
The conversion is still not complete; for simplicity, i2c_recv and
i2c_send (along with their wrappers) still take an adapter/address
pair. Fixing that would be complicated until the tests are converted
to qgraph, so it is left for after the conversion.

Provide *_init functions that populate an I2CAdapter struct without
allocating one, and make the existing *_create functions wrap them.
Because in the new setup *_create might return a pointer inside the
IMXI2C or OMAPI2C struct, create companion *_free functions to go
back to the outer pointer.
All this is temporary until allocation will be handled entirely by
qgraph.

If more than 4 bytes are received, the FIFO cannot host the entire
contents of the transfer and STP will be nonzero before entering
the transfer loop. Also, CNT will contain the number of bytes
left to be transferred instead of the total number of bytes in
the transfer.

The functions to read/write 8-bit or 16-bit registers are the same
in tmp105 and pca9552 tests, and in fact they are a special case of
"read block"/"write block" functionality; read block in turn is used
in ds1338-test.
Move everything inside libqos-test, removing the duplication. Account
for the small differences by adding to tmp105-test.c the "read register
after writing" behavior that is specific to it.

Currently, -accel help shows all possible accelerators regardless
if they are enabled in the binary or not. That is a different
semantic from -cpu and -machine helps, for example. So this change
makes it to list only the accelerators which support is compiled
in the binary target.
Note that it does not check if the accelerator is enabled in the

that. Also qtest is not displayed given that it is used for

Add a base class that is common to virtio-gpu and vhost-user-gpu

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.

PRD (Processor recovery diagnostics) is a service available on
OpenPower systems. The opal-prd daemon initializes the PowerPC
Processor through the XSCOM bus and then waits for hardware diagnostic
events.

Newer skiboots (after 6.3) support QEMU platforms that have
characteristics closer to real OpenPOWER systems. The CPU type is used
to define the BMC drivers: Aspeed AST2400 for POWER8 processors and
AST2500 for POWER9s.
Advertise the new platform property names, "qemu,powernv8" and
"qemu,powernv9", using the CPU type chosen for the QEMU PowerNV
machine. Also, advertise the original platform name "qemu,powernv" in
case of POWER8 processors for compatibility with older skiboots.
