extended to the feature format, or the all highest bits will be
unintentionally cleared.
Note that 'protocol_features' are not extended: they are only
used by vhost-user, and the latter device is not going to implement
extended features soon.

use any of them, serialize the full features range leveraging
newly introduced 128bits integer helpers.

Virtio features extend above the 64 bit space, and GSO over
UDP tunnels support is going to use some bits in the extended

Introduce a new Property type to handle the extended feature

The virtio specifications allows for up to 128 bits for the
device features. Soon we are going to use some of the 'extended'
bits features (above 64) for the virtio net driver.
For platform natively supporting 128 bits, introduce a 128 bit integer
state.
