The Worker struct is storing a Descriptor obtained from a timer for the
sole purpose of adding it to a WaitContext when the worker thread starts
running. Instead of doing this, create the WaitContext and pass it as
part of the worker data, so all ioctls involving that descriptor are
performed directly on the timer, guaranteeing that the descriptor is
valid.

Define constants for the end of the ranges that exist within the
settings BAR so we can use the range syntax in the match instead of
manually checking against the start and end.
This uses inclusive range (..=) syntax, since exclusive range pattern
syntax (..) is experimental. Therefore, each range has a `_LAST`
constant that is equal to the address of the last valid byte in that
range (first + size - 1).

On Unix, instead of getting random data from `/dev/urandom`, it will get
it from the `rand` platform agnostic crate instead.
OsRng.fill_bytes on unix will make a syscall to getrandom(2) if
available, otherwise it will read from `dev/urandom` after a succesful
poll to `dev/random`. Regardless of which way a random data is
retrieved, if the entropy pool is not intialized, `fill_bytes` will
block until it is intialized. This shouldn't be a problem because it is
a one time cost.

Use anyhow::Error instead of defining Error enum so that we can provide
more precise error messages easily.

Remove `Error::RxDescriptorsExhausted`, which was matched against.
As a result, no variants in `Error` enum appears in pattern matching and
we can switching to `anyhow::Error` easily in a following CL.

Main update is separating unix and windows to have their own `Block::new` constructor. Also made a `get_all_features` platform agnostic constructor helper since it can be shared on both platforms.

The biggest change is adding a platform agnostic constructor helper method
`BlockBackend::new_from_async_disk`. `BlockBackend::new` is moved to the
sys module since it's only used by Linux and Windows will have a
`BlockBackend::new_from_files` constructor.
Next step will be to upstream Windows vhost-user block vmm.

When a usb device is attached to guest kernel, guest kernel will
Try to set the usb configuration to value returned by
usb_choose_configuration. Unless the device has multiple configurations
and host side set it before attach to guest os, it will be same value
as what host kernel would set it during initialization. This would casue
a device reset and for Android devices in adb mode it will cause a
disconnect and reconnect.
Also we should allow user space trying to reset the device by setting
device configuration to active configuration.
