When creating a serial device of type UnixSocket crosvm will race with
vmlog_forwarder to bind a socket to the address. This is expected to
fail in most cases, so don't log an error message if it does unless
the reason was unexpected.
BUG=none
TEST=Booted termina and checked for logs about failing to bind sockets

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.

When opening the same output file for two serial devices (earlycon and
console), the output would be overwritten by the later device.
Change the file creation to use append mode so that the output file
contains all of the logs from both devices instead of overwriting it.
Tested with:
crosvm run \
--serial hardware=serial,type=file,console=false,earlycon=true,path=test.log \
--serial hardware=virtio-console,type=file,console=true,stdin=true,path=test.log \

This allows the creation of virtio-console devices using the new
hardware=virtio-console parameter to the --serial option.
Also add support for the serial earlycon option, which allows using
virtio-console as the main console device with a traditional serial
device as the early console. This allows logging during early boot
before PCI device discovery (when virtio-console devices are set up).

Also remove the new_in_out, new_out, and new_sink constructors for

Split the serial code into two parts:
- Configuration and setup: arch/src/serial.rs
- Serial device emulation: devices/src/serial.rs
No change in functionality - this is just preparation for generalizing
the command line parsing/setup code so that it can be used with virtio
console devices as well.
