[Daniel Henrique Barboza <danielhb@linux.vnet.ibm.com>]

v15:
- changed default endianess of sPAPREventLogEntry to native
- write the header fields and the extended_log directly in the guest memory

v14:
- several changes made in spapr_events.c to allow for a minimal VMSD to be
migrated. Please check the commit message of the patch for more information.

- data_size is now being calculated by using the extended_length field inside
rtas_event_log_queue

v12:
- patch 2: added a switch statement to get the proper data_size based on
the log_type

    * simplified the 'event_scan' function
- patch 2:
    * data_size is now calculated inside rtas_event_log_queue()
