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.

Sync events detected by android crashlog.
In android system, android crashlog is a log collection mechanism,
it will generate a history_event file to record android system events.
Acrnprobe will detect these events by scanning android history_event file.
This module mainly contains two functions:
1. setup loop device for android.img.
2. detect new event occursing in android.

The channel represents a way of detecting the system's events.
So far, there are 3 channels:
1. oneshot, detect once while acrnprobe startup.
2. polling, run a detecting job with fixed time interval.
3. inotify, watch the change of file or dir.
