Current mmio and device two allocators exist, the purpose to define
two allocator is:
Accessing to gpa from mmio allocator cause vm exit, while gpa from
device allocator doesn't cause vm exit.
Whether vm exits exist or not, dependency on whether
vm->add_device_memory() is called with gpa from allocator or not.Even
if gpa is from mmio alloator, and vm->add_device_memory() is called
with this gpa, accessing this gpa won't cause vm exit. So mmio allocator
and device allocator couldn't guarantee the original purpose.
This patch unify mmio allocator and device allocator into one mmio
allocator.

Adds support for virtio-pmem device as an alternative for virtio-blk.
Exposing disk image to guest as virtio-blk device results in both guest
and host independently caching the disk I/O. Using virtio-pmem device
allows to mount disk image as direct access (DAX) in the guest and thus
bypass the guest cache. This will reduce memory foodprint of the VMs.

AddressAllocator now maintains a HashMap<Alloc, (u64, u64, u64)>,
which uniquely maps a Allocation enum (e.g: PciBar(bus, dev, bar),
GpuRenderNode, etc...) to it's address, size, and human-readable tag
/ description.
The interface has also been modified to use Error instead of Option.
Aside from improving debugging, tracking allocations will have
numerous uses in the future. For example, when allocating guest memory
over VmControl sockets, it will be possible to restrict allocations to
pre-allocated slices of memory owned by the requesting device.
To plumb through PCI information to PCI devices, this CL necessitated
the addition of a PciDevice method called `assign_bus_dev`, which
notifies PCI devices of their uniquely assigned Bus and Device numbers.

AddressRanges' name doesn't suggest that it's a SystemAllocator builder.
This CL renames it to SystemAllocatorBuilder, and adds a
SystemAllocator::builder() that removes the need to have a separate
import for the Builder.
A minor change, but it cleans up the interface a bit.

In Rust 2018 edition, `extern crate` is no longer required for importing
from other crates. Instead of writing:
extern crate dep;
use dep::Thing;
we write:
use dep::Thing;
In this approach, macros are imported individually from the declaring
crate rather than through #[macro_use]. Before:
#[macro_use]
extern crate sys_util;
After:
use sys_util::{debug, error};
The only place that `extern crate` continues to be required is in
importing the compiler's proc_macro API into a procedural macro crate.
This will hopefully be fixed in a future Rust release.
extern crate proc_macro;

Found by running: `cargo rustc -- -D bare_trait_objects`
Bare trait objects like `&Trait` and `Box<Trait>` are soft-deprecated in
2018 edition and will start warning at some point.
As part of this, I replaced `Box<Trait + 'static>` with `Box<dyn Trait>`
because the 'static bound is implied for boxed trait objects.
