scripts: Test script to look for -device crashes
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.
