The only noticable change is using memory size in bytes for

Peter Krempa 9ac91fcceb qemuBuildChrDeviceCommandLine: Generate via JSON
Build commandlines for character devices via JSON.

For devices using 'VIR_DOMAIN_DEVICE_ADDRESS_TYPE_VIRTIO_SERIAL' address
type 'qemuBuildDeviceAddressProps' will now generate the address. The
only special property is 'nr'. QEMU declares it as:

  nr=<uint32>            -  (default: 4294967295)

The test fallout is caused by formatting addresses as decimal numbers
instead of hex as described in the commit which added

Peter Krempa a0d70f96ca qemuBuildControllersByTypeCommandLine: Generate via JSON
The handlers for PCI, SCSI and USB controllers already use JSON
internally. This patch converts 'virtio-serial', 'ccid' and 'sata' to do
the same and passes out the JSON directly so that it can be used in

special properties. QEMU thinks they have the following types:

Note that the legacy 'ivshmem' device was already removed upstream, but
it's converted so that the code is identical.

For the two modern devices QEMU considers the properties being of
following types:

  ioeventfd=<bool>       - on/off (default: true)

For convenience both the old and new are for now marked as unused, which
will be removed once the conversion is complete.

The formatted properties have following types according to QEMU.
'virtio-blk-pci' was used as an example:

Note that <OnOffAuto> is an enum type without alternates in QMP so it
must be represented as a string in JSON.
