[PATCH v5 0/5] ch: handle events from cloud-hypervisor

changes from v4->v5: * Incase of invalid events, exit VirCHEventHandler * Open eventmonitor fifo (Reader end) in virCHMonitorNew itself. This way, we can clean exit incase open fails for some reason. changes from v3->v4: * Don't abort; instead kill the VM and exit * use g_clear_pointer along with g_free * Fix possible memory leak changes from v2->v3: * Remove patch 'utils: Implement virFileIsNamedPipe' as it is no more needed. * Remove the eventmonitorpath only if it exists * Added domain name as a prefix to logs from ch_events.c. This will make debugging easier. * Simplified event parsing logic by reserving a byte for null char. changes from v1->v2: * Rebase on latest master * Use /* */ for comments * Remove fifo file if already exists * Address other comments from Praveen Paladugu cloud-hypervisor raises various events, including VM lifecylce operations such as boot, shutdown, pause, resume, etc. Libvirt will now read these events and take the necessary actions, such as correctly updating the domain state. A FIFO file is passed to `--event-monitor` option of cloud-hypervisor. Libvirt creates a new thread that acts as the reader of the fifo file and continuously monitors for new events. Currently, shutdown events are handled by updating the domain state appropriately.
