tools: Update endian definitions for Mac OSX
- it appears (at least from OS X verison 10.10, Yosemite) that the
big and little endian defintions have changed.
the older
#include <sys/_endian.h>
#include <architecture/byte_order.h>
reference yielded the following warning:
#define __bswap_16(x) NXSwapShort(x)
^
/usr/include/architecture/byte_order.h:45:1: note: 'NXSwapShort' has been explicitly marked deprecated here
For the new OS X editions, it seems that we need to refer to:
#include <netinet/in.h>
#include <libkern/OSByteOrder.h>
and respectively use 'OSSwapInt16', 'OSSwapInt32', & 'OSSwapInt64', in
place of 'NXSwapShort', 'NXSwapLong' & 'NXSwapLongLong'.
