This patch adds a visitor interface to Property. This way, QOM will be able to expose Properties that access a fixed field in a struct without exposing also the everything-is-a-string "feature" of qdev properties. Whenever the printed representation in both QOM and qdev (which is typically the case for device backends), parse/print code can be reused via get_generic/set_generic. Dually, whenever multiple PropertyInfos have the same representation in both the struct and the visitors the code can be reused (for example among all of int32/uint32/hex32).
