Add support for decoding sync_file_range

Browse Source 
* file.c (sync_file_range_flags): New xlat structure.
(sys_sync_file_range, sys_sync_file_range2): New functions.
* linux/syscall.h (sys_sync_file_range, sys_sync_file_range2): New
prototypes.
* linux/dummy.h (sys_sync_file_range, sys_sync_file_range2): Remove.
* linux/mips/syscallent-o32.h: Set the number of sync_file_range
arguments to 7.
