ch: Verify a disk's target bus type is supported

Currently only virtio types of buses are supported so check if the
configuration we are given matches.

ch: Handle resize events

When resize events are found in the monitor, try to update the thread
id mapping (if a change is detected the domain.xml will also be
updated).

On vm resizes removing vcpus, the event will be triggered but because
cloud-hypervisor does not kill the associated thread right away, the
thread of the removed vcpu is going to still be detected and so
validating the event was processed successfully is skipped for now.

Fix compilation errors

Add reconnect support for CH

Allow CH domains to be reconnected to after restarting libvirt. This
change enables the creation of the pidfile and domain definiton file
alongside the socket file. With these files in place (and getting
updated). The CH domain is now able to track what domains were running
when libvirt was closed. From there add the matching restore code to
allow the VM state to be read in and processed by libvirt.

Changes to hardware device management will necessitate more
development on this feature in order to track the state of different
devices in use (this is fairly different than the equivalent QEMU
code).

ch: procfs watcher thread for updating vm's thread information

Implement a thread that parses procfs for any changes to the VM
process's threads and on any change, update the thread information
maintained by the monitor.
