Since ACRN has the capability to reboot and reboot reason is available
in SOS, acrnprobe could detect the crash of acrn and SOS kernel.
List of added crash types:
1. ACRNCRASH - crashed in hypervisor, this detection depends on
files in /tmp/acrnlog_last(provided by acrnlog).
2. IPANIC - crashed in SOS kernel, this detection depends on
pstore.
3. SWWDT_IPANIC - crashed in SOS kernel and reboot reason is wdt.
4. HWWDT_UNHANDLE - only recognize reboot reason is global, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.
5. SWWDT_UNHANDLE - only recognize reboot reason is wdt, there is no

In the original design, acrnprobe marked all handled VMs'events as "synced"
in file vmrecordid(this patch changes the name to VM_eventsID.log).
Currently, the Android log events are not logged if the first attempt at
reading collecting them from the VM fails. This patch changes the logic
so that the acrn-crashlog tool will retry continuously.
This patch defines different tags for handled VMs'events, and only marks
VMs'events "synced" after it returns successfully.
