This patch refines the process of log space check.
Check a folder's size need to traverse all nodes of files and subdirs,
in the case of extreme memory strain, accessing these log file nodes
frequently will increase the IO pressure on the eMMC.
Previously, all log files will be accessed and counted in each space
check, this patch refines it by only calculating the increment of new logs.

This patch introduce the command `crashlogctl`,
it is used to enable/disable the ACRN crashlog services.
Also a systemd-tmpfile config file is introduced to create the
/var/log/crashlog directory, and a sysctl config file where
the usercrash-wrapper will be configured at boot time.

This patch adds the usercrash client in the pipe of core_pattern
without affecting default core_pattern program.
In acrnprobe_prepare.sh, core_pattern will be set as usercrash-wrapper
with all of the arguments, which parses the parameters of the default
core_pattern program and the usercrash client, and then invokes them
separately.

This patch is to improve the way of updating the core_pattern content
in the shell script, since the previous configuration in core_pattern
will block coredumpctl.
This patch adds an inspection before changing the content of
core_pattern.

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.

This patch is to change the source of config file according
to the doc of telemetrics-client:
There is a config file installed at
``/usr/share/defaults/telemetrics/telemetrics.conf``
To make modifications, copy that file to
``/etc/telemetrics/telemetrics.conf``
and modify the /etc version.
Otherwise, the modification may be lost after ``swupd update``.
