In order to reuse the SystemAllocator later at runtime, it is moved into
the new structure AddressManager. The goal is to have a hold onto the
SystemAllocator and both IO and MMIO buses so that we can use them
later.

In order to support PCI BAR reprogramming, the PciDevice trait defines a
new method move_bar() dedicated for taking appropriate action when a BAR
is moved to a different guest address.

Packages are a way of grouping values together and as such they require
an explicit length which is a variable length encoding calculated with

A new ClearLinux image has been uploaded to the Azure storage account.
It is based off of the ClearLinux cloudguest image 31310 version, with
two extra bundles added to it.
First bundle is sysadmin-basic to include utility like netcat, and the
second bundle is iperf, adding the iperf binary to the image.
The image is 2G in size.

This patch extends the existing virtual IOMMU documentation, explaining
how the use of huge pages can drastically improve the VM boot time.
Particularly, how in case of nested VFIO, the impact is significant and
the rationales behind it.
