The support for the 'ioeventfd' knob of virtio devices was introduced by
QEMU commit 25db9ebe15125 contained in v0.14.0-rc0 and it can't be
compiled out. Thus libvirt can assume it's support and remove
conditional code.

Introduce infrastructure to format 'drive' addresses via the standard
helper rather than hand-rolled generators used inline.
The code needs to know the disk bus to format the correct address which
is passed in via an internal field in virDomainDeviceDriveAddress.
The field types according to QEMU are as following:
'ide-hd' for VIR_DOMAIN_DISK_BUS_IDE and VIR_DOMAIN_DISK_BUS_SATA
unit=<uint32> - (default: 4294967295)
'floppy' for VIR_DOMAIN_DISK_BUS_FDC

Upcoming patches will start converting the formatting of arguments for
-device from a string to JSON so that we can keep proper types around
when using it via QMP.
This means we will need an equivalet for the device address builder
function. 'qemuBuildDeviceAddressProps' provides equal functionality,
but the output differs for fields where a number is expected, where
we've previously formatted a hex value but now end up with a decimal
value per JSON standard.
For given address types I've selected an example device and used
'-device $DEV,help' to obtain the current types recognized by qemu:
Note that 'bus' is not shown below, but it's already a string so we can
keep using it as a string.
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI (virtio-balloon-pci)
acpi-index=<uint32> - (default: 0)
addr=<int32> - Slot and optional function number, example: 06.0 or 06 (default: -1)
multifunction=<bool> - on/off (default: false)
Note that 'addr' is here defined as 'int32' but in fact internally in
qemu is an alternate type between a number and a string so we can keep
using strings here.
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_USB (usb-tablet)
port=<str>
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_SPAPRVIO (spapr-vty)
reg=<uint32> - (default: 4294967295)
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_CCW (virtio-blk-cww)
devno=<str> - Identifier of an I/O device in the channel subsystem, example: fe.1.23ab
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_ISA (isa-serial)
iobase=<uint32> - (default: 4294967295)
irq=<uint32> - (default: 4294967295)
VIR_DOMAIN_DEVICE_ADDRESS_TYPE_DIMM (pc-dimm)
slot=<int32> - (default: -1)
