For ioctl numbers that do not require any parameters, make ioctl_io_nr
and related macros generate a constant rather than a function with no
parameters. This makes the code that uses these constants more idiomatic
and also allows using the constants in match statements (see an example
in virtio/fs/passthrough.rs).

Ensure that every Cargo.toml dependency on a third-party crates.io crate
specifies at least a major version, or a minor version for 0.x crates,
to ensure that if a new major version is published, it cannot cause API
breaks.
The versions are selected to match the ones already in Cargo.lock, so
this should have no functional change, but it will help prevent new "*"
versions from being introduced via copy-and-paste.
For rationale, see the Cargo FAQ:
<https://doc.rust-lang.org/cargo/faq.html#can-libraries-use--as-a-version-for-their-dependencies>
`minijail`, `audio_streams`, and `cras` are left as "*" for now, since
they have unusual situations (imported from a submodule and/or replaced
at build time with ebuild magic).

This is a workaround for a bug encountered with newer Android phones -
when connected to the Linux VM, resetting the USB device via
USBDEVFS_RESET causes the device to disconnect from the host, preventing
its use in the VM.
This works around the issue by removing both paths that can cause a
USB device reset (initial reset at device insertion plus reset when
requested by the guest kernel). Both of these must be removed to
restore functionality; if either is still in place, the failure is still
observed.
The workaround specifically exempts Edge TPU devices, which need a reset
for firmware update; these devices will still issue a reset on connect
and when requested by the guest.

On devices with only one configuration, skip the code that attempts to
change the device's active configuration, since it must always be the
single available configuration.
This works around an issue observed with some USB devices (e.g. Servo
Micro) where the initial Get Configuration control request fails with
-EPIPE.

The new USB descriptor parsing code is a nice candidate for a fuzzer,
since it takes an arbitrary stream of bytes as input and parses it.

Drop the dependency on libusb and reimplement the host USB backend using
usb_sys to wrap the Linux usbdevfs ioctls.
This allows sandboxing to work without any dependency on libusb patches,
and it gives us the flexibility to modify and update the USB backend
without depending on an external third-party library.

Rather than having a get_canceller() function on UsbTransfer, make the
submit function return the canceller. This makes it clear that the
transfer can't be cancelled before it is submitted.

Replace use of our custom, patched libusb APIs with the new
libusb_wrap_sys_device() function, which has been submitted to libusb
upstream. This allows us to drop the bindings for the custom APIs (and
will also allow us to drop the libusb patch that introduces them).
For now, keep this path behind the sandboxed-libusb feature to allow
crosvm to build against older libusb versions that do not have the new
API. This should be cleaned up eventually once we are comfortable with
raising the minimum libusb version required.
