If a control request has a DataStage, execute the request during the
data stage so that we can get the actual length of the transferred data.
This will allow the ISP (Interrupt on Short Packets) bit to be
implemented correctly; we need to know the actual length during
processing of the DataStage TRB rather than at the StatusStage as we did
previously. (Note that ISP isn't implemented yet in this change; this
just passes the correct length to xhci_transfer.on_transfer_complete,
which doesn't do anything useful with the length yet in the short
transfer case.)

Certain control requests need to be intercepted for special handling
rather than being passed through directly to the device. Clean up the
implementation of these intercepted requests by getting rid of the
confusing intermediate analyze_request_setup function and merging it
with the actual handling of each intercepted request in the new
execute_control_transfer function. This keeps the custom handling all
in one place rather than scattered around the file and removes the need
for the extra HostToDeviceControlRequest enum.
Also add a check in get_standard_request to verify that the request is
indeed a standard control request so that the caller does not need to
check.

The UsbHub::try_detach function, which is only called from the libusb
hotplug callback when devices are removed, calls into
port.get_backend_device(), which acquires the backend_device lock, and
then calls port.detach(), which also tries to acquire the backend_device
lock, while still holding onto the backend_device. This clearly leads to
a deadlock.
Add an extra block in try_detach to keep the backend_device lock scoped
so that it is dropped before calling port.detach().

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.

In Rust 2018 edition, `extern crate` is no longer required for importing

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.
