2012-02-29memory: support stateless memory listenersAvi Kivity
Current memory listeners are incremental; that is, they are expected to maintain their own state, and receive callbacks for changes to that state. This patch adds support for stateless listeners; these work by receiving a ->begin() callback (which tells them that new state is coming), a sequence of ->region_add() and ->region_nop() callbacks, and then a ->commit() callback which signifies the end of the new state. They should ignore ->region_del() callbacks. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-02-29memory: split memory listener for the two address spacesAvi Kivity
The memory and I/O address spaces do different things, so split them into two memory listeners. Signed-off-by: Avi Kivity <avi@redhat.com>

2012-02-29memory: don't pass ->readable attribute to cpu_register_physical_memory_logAvi Kivity

2012-02-29memory: add a readonly attribute to MemoryRegionSectionAvi Kivity
.readonly cannot be obtained from the MemoryRegion, since it is inherited from aliases (so you can have a MemoryRegion mapped RW at one address and RO at another).

2012-02-07qdev: allow reusing get/set for legacy propertyPaolo Bonzini
In some cases, a legacy property does need a special print method but not a special parse method. In this case, we can reuse the get/set from the static (non-legacy) property. If neither parse nor print is needed, though, do not register the legacy property at all. The previous patch ensures that the right fallback will be used.

2012-02-07qdev: remove direct calls to print/parsePaolo Bonzini
There's no need to call into ->parse and ->print manually. The QOM legacy properties do that for us. Furthermore, in some cases legacy and static properties have exactly the same behavior, and we could drop the legacy properties right away. Add an appropriate fallback to prepare for this.

2012-02-07qom: use object_resolve_path_type for linksPaolo Bonzini
This allows to restrict partial matches to objects of the expected type. It will let people use bare names to reference drives even though their name might be the same as a device's (e.g. -drive id=hd0,if=none,... -device ...,drive=hd0,id=hd0). As a useful byproduct, this fixes a problem with links of interface type. When a link property's type is an interface, the code expects the implementation object (not the parent object) to be stored in the variable. The parent object does not contain the right vtable.
