This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.
