The virtio-fs virtio device provides shared file system access using
the FUSE protocol carried over virtio.
The actual file server is implemented in an external vhost-user-fs device

The ACPI Generic Event Device (GED) is a hardware-reduced specific
device[ACPI v6.1 Section 5.6.9] that handles all platform events,
including the hotplug ones. This patch generates the AML code that
defines GEDs.

Platforms need to specify their own GED Event bitmap to describe
what kind of events they want to support through GED.  Also this
uses a a single interrupt for the  GED device, relying on IO
memory region to communicate the type of device affected by the
interrupt. This way, we can support up to 32 events with a unique
interrupt.

This supports only memory hotplug for now.

Everybody who used something like "-machine accel=kvm:tcg" in the past
might be tempted to specify a similar list with the -accel parameter,
too, for example "-accel kvm:tcg". However, this is not how this
options is thought to be used, since each "-accel" should only take care
of one specific accelerator.

In the long run, we really should rework the "-accel" code completely,
so that it does not set "-machine accel=..." anymore internally, but
is completely independent from "-machine". For the short run, let's
make sure that users cannot use "-accel xyz:tcg", so that we avoid
that we have to deal with such cases in the wild later.
