qom: add new command to search for types
This adds a command that allows searching for types that implement a property. This allows you to do things like search for all available PCIDevices. In the future, we'll also have a standard interface for things with a BlockDriverState property that a PCIDevice could implement. This will enable search queries like, "any type that implements the BlockDevice interface" which would allow management tools to present available block devices without having to hard code device names. Since an object can implement multiple interfaces, one device could act both as a BlockDevice and a NetworkDevice. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
