qapi: New -compat deprecated-input=crash
Policy "crash" calls abort() when deprecated input is received. Bugs in integration tests may mask the error from policy "reject". Provide a larger hammer: crash outright. Masking that seems unlikely. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20210318155519.1224118-12-armbru@redhat.com>
