hw/core: create Resettable QOM interface This commit defines an interface allowing multi-phase reset. This aims to solve a problem of the actual single-phase reset (built in DeviceClass and BusClass): reset behavior is dependent on the order in which reset handlers are called. In particular doing external side-effect (like setting an qemu_irq) is problematic because receiving object may not be reset yet. The Resettable interface divides the reset in 3 well defined phases. To reset an object tree, all 1st phases are executed then all 2nd then all 3rd. See the comments in include/hw/resettable.h for a more complete description. The interface defines 3 phases to let the future possibility of holding an object into reset for some time. The qdev/qbus reset in DeviceClass and BusClass will be modified in following commits to use this interface. A mechanism is provided to allow executing a transitional reset handler in place of the 2nd phase which is executed in children-then-parent order inside a tree. This will allow to transition devices and buses smoothly while keeping the exact current qdev/qbus reset behavior for now. Documentation will be added in a following commit.
