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
further clues that it's a SOS kernel crash or a
hypervisor crash.
6. UNKNOWN - only recognize reboot reason is warm, there is no
further clues that it's a SOS kernel crash or a
hypervisor crash.

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.

This patch is to fix potential issues, which are reported by static
analysis tool, for acrnprobe.
Changes:
1. Check the return value of sender_id() and get_sender_by_name(),
since it could be -1 or NULL.
2. Remove the parameter len from create_event, take parameter path
as a NULL-terminated string as default.
3. Modify for_each_* functions to avoid overflow.

Running 'make' will leave 3 files in the source code tree that
are not cleaned by a subsequent 'make clean'. These are:
* tools/acrn-crashlog/acrnprobe/include/version.h
* tools/acrn-crashlog/usercrash/include/version.h
* tools/acrn-manager/acrn_mngr.o
(as reported by 'git status' after 'make')
This patch changes the location of these files so they are
created in the target build directory and hence properly
cleaned when running 'make clean'
Other minor changes to the Makefiles include:
* Remove BASEDIR by the built-in CURDIR variable
* Add .PHONY targets

2. polling, run a detecting job with fixed time interval.
3. inotify, watch the change of file or dir.
