commit c8813b3175a3dcca159e1194bb851e7edebad6a7
Author: Hung-Te Lin 
Date:   Wed Mar 13 18:08:29 2013 +0800

libpayloads: Provide BSD/glibc style endian functions.

The functions in endian.h (betoh{l,w,ll} and others) were named differently from
    the well-known BSD/glibc style endian functions (ex, betoh{16,32,64}). We should
    provide the BSD/glibc style functions to prevent confusion.
