defc33927f docs: iommu: Improve VM boot time and performance
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.

5fc3f37c9b vmm: Add iommu=on|off option for --device
Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a VFIO device should be attached to the virtual
IOMMU or not. That's why we introduce an extra option "iommu" with the
value "on" or "off". By default, the device is not attached, which means
"iommu=off".

device. This is important to understand what the use cases are for this
new device and how to properly use it with virtio devices.

4b8d7e718d vmm: Add iommu=on|off option for --disk
Having the virtual IOMMU created with --iommu is one thing, but we also
need a way to decide if a virtio-blk device should be attached to this
virtual IOMMU or not. That's why we introduce an extra option "iommu"
with the value "on" or "off". By default, the device is not attached,
which means "iommu=off".

One side effect of this new option is that we had to introduce a new
option for the disk path, simply called "path=".

74a21f24e1 vendor: Remove vendoring
The cargo interaction with the .cargo/config does not meet our
requirements.

Regardless of .cargo/config explicitly replacing our external sources
with vendored ones, cargo build will rely first on Cargo.lock to update
its local source cache. If a dependency has been push forced, build
fails because of our top level Cargo.toml description.
This prevents us from actually pinning dependencies, which defeats the
vendoring purpose.

We're removing vendoring for now, until we understand it better.
