[PATCH 0/2] Enable QMP Dumping for testimage

[Saul Wold]

This is the forth (and maybe final) pass at enabling getting debug
information from QEMU via the Qemu Machine Protocol interface. The
Qemu source provides a qmp.py module which is installed in the 
recipe-sysroot-native site-packages.

The initial commands that are issued to qmp when a failure is detected
are: query-status and query-block. The output goes into formated json
files as follows:

tmp/log/runtime-hostdump/202101061054_qmp
├── qmp_00_query-block
├── qmp_00_query-status
├── qmp_01_query-block
└── qmp_01_query-status

This has been tested by calling the monitor_dump code directly in the
target/ssh.py code instead of waiting for a given failure.

This version adds a time-out loop to check for the Unix Socket file
that was being problematic on the CentOS-8 builders.

Sau!

[PATCH 1/2] qemu-system-native: install qmp python module

[Saul Wold]

The qmp python module supports the Qemu Machine Protocol [0].
This module needs to be installed in a known location so the
qemurunner python script can find the qmp module.

This change causes it to be installed in the recipe-sysroot-native
of the target image and that directory can be added to the python
sys.path that needs to use the qmp.py module.

[PATCH 2/2] qemurunner: Add support for qmp commands

[Saul Wold]

This adds support for the Qemu Machine Protocol [0] extending
the current dump process for Host and Target. The commands are
added in the testimage.bbclass.

Currently, we setup qemu to stall until qmp gets connected and
sends the initialization and continue commands, this works
correctly. If the UNIX Socket does not exist, we wait an timeout
to ensure to socket file is created.

With this version, the monitor_dumper is created in OEQemuTarget
but then set in OESSHTarget as that's where we get the SSH failure
happens. Python's @property is used to create a setter/getter type
of setup in OESSHTarget to get overridden by OEQemuTarget.

By default the data is currently dumped to files for each command in
TMPDIR/log/runtime-hostdump/<date>_qmp/unknown_<seq>_qemu_monitor as
this is the naming convenstion in the dump.py code.

We use the qmp.py from qemu, which needs to get installed in the
recipe-sysroot-native of the target image.

[PATCH 1/2] qemu-system-native: install qmp python module

[Saul Wold]

The qmp python module supports the Qemu Machine Protocol [0].
This module needs to be installed in a known location so the
qemurunner python script can find the qmp module.

This change causes it to be installed in the recipe-sysroot-native
of the target image and that directory can be added to the python
sys.path that needs to use the qmp.py module.
