tests/functional: add a QMP backdoor for debugging stalled tests
Support the QEMU_TEST_QMP_BACKDOOR=backdoor.sock env variable as a way to get a QMP backdoor for debugging a stalled QEMU test. Most typically this would be used if running the tests directly: $ QEMU_TEST_QMP_BACKDOOR=backdoor.sock \ QEMU_TEST_QEMU_BINARY=./build/qemu-system-arm \ PYTHONPATH=./python \ ./tests/functional/test_arm_tuxrun.py And then, when the test stalls, in a second shell run: $ ./scripts/qmp/qmp-shell backdoor.sock Signed-off-by: Daniel P.
