Along with this rename comes updating all usages to the
appropriate RawDescriptor traits. As per usual it touches
many files, but makes no significant changes.
The only remaining instance of "keep_fds" is to call out to
3p lib adhd.

Virtio 1.1 introduces the VIRTIO_F_ACCESS_PLATFORM reserved feature bit,
which allows the guest operating system to discover that a virtio device
has limited access to memory. In the case of Linux, this forces the use
of the DMA API for virtio transfers, which in turn can bounce data
through a shared window that is negotiated between the guest and the
hypervisor.
Advertise the VIRTIO_F_ACCESS_PLATFORM reserved feature bit when crosvm
is running with the '--protected-vm' option.

Note the CL size is large entirely due to the rename,
the changes are mostly negligible.
Also making a few small additional changes in sys_util
areas that don't need much attention in base. This includes
typedefing and adding specific imports for areas that don't
require significant interface changes.

For now, this crate simply re-exports all of sys_util, but it will
be updated to provide new interfaces when needed. This is the
first step to making crosvm not directly depend on sys_util, so
that we can make the interface changes we need without fear of
negatively affecting (i.e. completely breaking) other usages
within chromeos.

This will be used to allow generic code to create serial devices as well
as virtio-console devices.
Also remove the new_in_out, new_out, and new_sink constructors for
Serial and Console, since they are not used anywhere.
