Eduardo Habkost 44d815e83a device-crash-test: New known crashes 
We are not running the script on "make check" yet, and additional
bugs were introduced recently in the tree.

Whitelist the new crashes while we investigate, to allow us to
run device-crash-test on "make check" as soon as possible to
prevent new bugs.

# Purposes of the following whitelist:
# * Avoiding verbose log messages when we find known non-fatal
# (exitcode=1) errors
# * Avoiding fatal errors when we find known crashes
# * Skipping machines/devices that are known not to work out of
# the box, when running in --quick mode
#
# Keeping the whitelist updated is desirable, but not required,
# because unexpected cases where QEMU exits with exitcode=1 will
# just trigger a INFO message.
# Valid whitelist entry keys:
# * accel: regexp, full match only
# * 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
# * warn: if True, matching failures will be logged as warnings
# * expected: if True, QEMU is expected to always fail every time
# when testing the corresponding test case
# * loglevel: log level of log output when there's a match.
