Since we can't test mshv and kvm at the same time, --all-features no
longer work.
We factorize all, non-hypervisor related features into a common set and
mix that with either mshv and kvm.

This is the initial folder structure of the mshv module inside
the hypervisor crate. The aim of this module is to support Microsoft
Hyper-V as a supported Hypervisor.

Unfortunately it seems patch entries are ignored when obtaining
dependencies from another workspace.
Remove the problematic kvm-ioctls and kvm-bindings patch entries and use
the forked repository directly.

Instead of waiting blindly with fixed amount of sleeping time, we can
use the `wait-timeout` crate to explicitly wait VM shutdown (with a
timeout). It can reduces the execution time of some tests
substantially. Also, this patch increases the `shutdown` timeout for
'test_reboot', which should fix the recent sporadic failures on this
test.

Instead of blindly waiting for 20-40s for the guest VM to boot, this
patch waits the notification from the guest VM explicitly by using a
simple TcpListener on the host and a custom systemd service in the
guest.
This patch also ported few tests to use this new machanism, while more
tests are to be ported.

Use a Result<> type with an error to simplify the code in start_vmm().
This will also make it easier to add cleanup funtionality.

Now that we that our CI is running with a kernel that is new enough to
support io_uring we can turn this feature on by default.

Split out the HTTP request handling code from ch-remote into a new

Instead of having the hypervisor crate embedding Cloud-Hypervisor forks
from the rust-vmm project, it's more appropriate to leave the rust-vmm
references in the hypervisor crate, and have the root Cargo.toml being
patched.

The Cloud-Hypervisor fork of the vhost crate contains one small
additional patch compared to the rust-vmm upstream version, meant for
increasing the connection timeout.
This patch is intended to be merged in order to check if it helps our CI
fixing the vhost-user-blk flakes that we've been observing recently.
If it fixes it, we'll submit a similar patch upstream and switch back to
the upstream vhost crate, otherwise we'll simply switch back to the
upstream crate, discarding this patch.

In our build-script (build.rs), we won't set the environment variable
'BUILD_VERSION' when the 'git describe' command failed (e.g. when the
current source tree does not contain git information). This patch added
a fall back path where the default value of 'BUILD_VERSION' is based on
the 'cloud-hypervisor' crate version.

By adding a new io_uring feature gate, we let the user the possibility
to choose if he wants to enable the io_uring improvements or not.
Since the io_uring feature depends on the availability on recent host
kernels, it's better if we leave it off for now.
As soon as our CI will have support for a kernel 5.6 with all the
features needed from io_uring, we'll enable this feature gate
permanently.

Remove the vmm dependency from vhost_user_block and vhost_user_net where
it was existing to use config::OptionParser. By moving the OptionParser
to its own crate at the top-level we can remove the very heavy
dependency that these vhost-user backends had.
