[PATCH v2-resend 01/30] libxl: Add LIBXL_SHUTDOWN_REASON_UNKNOWN

[Rob Hoes <rob.hoes@citrix.com>]

libxl_dominfo.shutdown_reason is valid iff (shutdown||dying). This is a bit
annoying when generating language bindings since it needs all sorts of special
casing. Just introduce an explicit value instead.
