Store all VMs together.

In preparation for the primary VM becoming less special, particularly in
the context of IPC where any VM will be able to talk to any other VM.
The primary VM takes ID 0 and the secondary VMs take the IDs from 1.

`hf_vm_get_count()` now returns the total number of VMs including the
primary.

`hf_rpc_request()` block reflexive calls as there is no good reason for
them and the error has the chance of catching bugs in the calling VM.
