Currently `arch` crate cannot be built, by specifying `hypervisor/kvm`
to turn on the features required for its dependency - `hypervisor` crate
to build. Thus enabling `arch` crate to be built with command:
```sh

AddressManager::move_bar() acquires the device_tree mutex.
The function is called from PciConfigIo::config_space_write()/
PciConfigMmio::config_space_write() while the pci_bus mutex
is acquired.
The functions DeviceManager::pci_resources()/eject_device()
acquire these mutexes in reverse order, which leads to a deadlock.
Fixes: #6775

This lint disallows asserttions on is_ok()/is_err() in favor of either
using unwrap (so that at least if the test fails, we the failure message
will contain the actual failure reason instead of just "was not
ok/err"), or actually matching the specific variant.
Inspired by and quoted from @roypat.
Enable this lint for `build.yaml` and `quality.yaml`.

Asserting on .is_ok()/.is_err() leads to hard to debug failures (as if
the test fails, it will only say "assertion failed: false". We replace
these with `.unwrap()`, which also prints the exact error variant that
was unexpectedly encountered (we can to this these days thanks to
efforts to implement Display and Debug for our error types). If the
assert!((...).is_ok()) was followed by an .unwrap() anyway, we just drop
the assert.

Enforcing group_imports="StdExternalCrate" requires using cargo fmt from
the nightly toolchain. Create a new workflow that runs on nightly to run
cargo fmt.
Signed-off-by: Rob Bradford <rbradford@rivosinc.com>
Historically the Cloud Hypervisor coding style has been to ensure that
all imports are ordered and placed in a single group. Unfortunately
cargo fmt has no support for ensuring that all imports are in a single
group so if whitespace lines were added as part of the import statements
then they would only be odered correctly in the group.
By adopting "group_imports="StdExternalCrate" we can enforce a style
where imports are placed in at most three groups for std, external
crates and the crate itself. Choosing a style enforceable by the tooling
reduces the reviewer burden.

For a VM with virt-console enabled, when a reboot is requested, the
console devices are closed during the shutdown path. As part of this
the sigwinch listener process and the console resizer pipe are closed.
For the new incarnation of the VM, fresh set of console devices are
setup and a new console resizer pipe is created. The new VM should
be setup to use the newly created console devices including the console
resizer pipe.
Reading from the older console resizer pipe results in unexpected eof
error and terminates the cloud hypervisor process.
