qapi: Convert query-status
Please, note that the RunState type as defined in sysemu.h and its runstate_as_string() function are being dropped in favor of the RunState type generated by the QAPI. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
