gsmhr-cod2hex: read native endian by default Let's change gsmhr-* utilities to read *.cod and *.dec files in the local machine's native byte order by default, and support both -b and -l override options. This approach is the only sane one when we write *.cod and *.dec files in the local endian.

/*
 * This header file defines the interface to our utility function
 * that determines the local machine's native byte order, thereby
 * providing a default for file reading functions that can be overridden
 * with -b or -l options.
