may be shared with other helpers.

The WIP specification is hosted on slirp wiki at this point:
https://gitlab.freedesktop.org/slirp/libslirp/-/wikis/Slirp-Helper
We would need more feedback from various parties (including libvirt,
podman, and other developpers) before declaring a frozen version.
So for now, follow it, and feedback welcome!

When the helper supports DBus, connect it to the bus and set its ID.
If the helper supports migration, register its ID to the list of
dbus-vmstate ID to migrate, and specify --dbus-incoming when
restoring the VM.

This code was based on a per-helper instance and peer-to-peer
connections. The code that landed in qemu master for v5.0 is relying
on a single instance and DBus bus.
Instead of trying to adapt the existing dbus-vmstate code, let's
remove it and resubmit. That should make reviewing easier.

Now, that we know that the slirp helper will have the pidfile
open and locked we can use virPidFileForceCleanupPath() to kill
it and unlink the pidfile.

directly instead of our custom aliases.
