By default, QEMU will allow devices to be plugged into a bus up to the bus class's device count limit. If the user creates a device on the command line or via the monitor and doesn't explicitly specify the bus to plug it in, QEMU will plug it into the first non-full bus that it finds. This is fine in most cases, but some machines have multiple buses of a given type, some of which are dedicated to on-board devices and some of which have an externally exposed connector for user-pluggable devices. One example is I2C buses. Provide a new function qbus_mark_full() so that a machine model can mark this kind of "internal only" bus as 'full' after it has created all the devices that should be plugged into that bus. The "find a non-full bus" algorithm will then skip the internal-only bus when looking for a place to plug in user-created devices.
