Liu, Xinwu 876cc68311 tools:acrn-crashlog: Change the algorithm of generating event key
Acrnprobe is using SHA to generate ids for events. These ids are only used

David B. Kinder 348422dba6 doc: fix graphviz scanning and processing
The doc build process copies files using script/extract-content.py from
outside of the doc/ folder (specifically content in the tools/ folders).
The script was not copying graphviz directive files.  This has been
fixed and the embedded graphviz directives are not (properly) stored in
separate image/*.dot files.

Note the extract-content.py file is derived from the Zephyr project.

The ``.. code-block::`` directive can specify a highlight language for

"console" were the same, but we're now using "console" for creating
terminal-looking output (rather than doing images of terminal windows)
with a black background and white text.

This PR replaces unintended uses of the "console" highlighting language

Liu, Xinwu b30ba3db15 tools:acrn-crashlog: Detect and classify the crash in ACRN and kernel
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.

Liu, Xinwu 41b39c5e1f tools: acrn-crashlog: Defer the vm events processing when failed
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.
