Test code to check if we can crash QEMU using -device. It will
test all accel/machine/device combinations by default, which may
take a few hours (it's more than 90k test cases). There's a "-r"
option that makes it test a random sample of combinations.
The scripts contains a whitelist for: 1) known error messages
that make QEMU exit cleanly; 2) known QEMU crashes.
This is the behavior when the script finds a failure:
* Known clean (exitcode=1) errors generate DEBUG messages
(hidden by default)
* Unknown clean (exitcode=1) errors will generate INFO messages
(visible by default)
* Known crashes generate error messages, but are not fatal
(unless --strict mode is used)
* Unknown crashes generate fatal error messages
Having an updated whitelist of known clean errors is useful to make the
script less verbose and run faster when in --quick mode, but the
whitelist doesn't need to be always up to date.

Changes v2 -> v3:
* Renamed to scripts/device-crash-test (removed .py suffix)
* Changed license to GPLv2+
* whitelist updates:
* New whitelist entries
* Documented whitelist expectations more clearly
* Use loglevel=INFO on unknown exitcode=1 cases
* Ignore ide-cd errors on older QEMU versions
* Refactor of whitelist lookup code to make it clearer
* Optimization: when in quick mode, check if machine is usable before
testing it using -device
* Run in verbose mode by default
* Include exception traceback on the log output.
* Use lowercase on "skipped:" message for consistency
* Run on quick mode by default
* Added --strict option
* Don't crash if -r argument is too large
* Eliminate useless genAllCases() wrapper function
* Eliminate dead pickRandomCase() function
* Eliminate dead debugging code
* Include exception details on debug log if a machine fails to run
* Removed code that tries to detect obsolete entries
* Update commenst to mention user_creatable instead of the old
cannot_instantiate_with_device_add_yet name
* Coding style updates to make pylint and pep8 happier
Changes v1 -> v2:
* New whitelist entries:
* "could not find stage1 bootloader"
* Segfaults when using devices: a15mpcore_priv, sb16, cs4231a, arm-gicv3
* Format "success" line using formatTestCase(), and using DEBUg
loglevel
* Reword "test case:" line with "running test case:", for clarity
* Fix "pc-.*" whitelist to include "q35" too
* Add --devtype option to test only a specific device type
* Send all log messages to stdout instead of stderr
* Avoid printing "obsolete whitelist entry?" messages if we know
we are not testing every single accel/machine/device
combination
* --quick mode, to skip cases where failures are always expected,
and to print a warning in case we don't get an expected failure
* Use qemu.QEMUMachine instead of qtest.QEMUQtestMachine, as we don't
use any of the QEMUQtestMachine features
* Fix handling of multiple '-t' options
* Simplify code that generate random sample of test cases

+# * Avoiding fatal errors when we find known crashes
+# * Skipping machines/devices that are known not to work out of

+# Keeping the whitelist updated is desirable, but not required,

+# * machine: regexp, full match only
+# * device: regexp, full match only
+# * log: regexp, partial match allowed
+# * exitcode: if not present, defaults to 1. If None, matches any exitcode

+# * expected: if True, QEMU is expected to always fail every time
