Add a key-value interface to pvbus(4) that allows to get or set values
in the underlying information store of the host from the OpenBSD-VM's
userspace. OpenBSD did not provide access to these stores before,
mostly because we did not want to add a custom tool and interface for
each hypervisor. The pvbus(4) interface provides backends for
xen(4)'s XenStore and vmt(4)'s VMware Tools "guestinfo". These
information stores are fairly different, XenStore is a "filesystem"
while vmt is a RPC, and the key-value abstraction limits them a bit
but provides the most wanted functionality.
