memory: make section size a 128-bit integer

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes...

qdev: fix get_fw_dev_path to support to add nothing to fw_dev_path

Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path...

virtio-pci: fix level interrupts

mask notifiers are never called without msix,
so devices with backend masking like vhost don't work.

virtio: properly validate address before accessing config

There are several several issues in the current checking:

- The check was based on the minus of unsigned values which can overflow
- It was done after .{set|get}_config() which can lead crash when config_len...

virtio-x-bus: force bus name to virtio-bus.

When the proxy id is set, this bus takes the name "id.0" which is expected
to be the virtio-device's first bus.

So force this name to "virtio-bus" as it is an internal bus.
