Rationalize endianness macros
Extend the endianness macros to support systems that define them in
<sys/param.h> and replace the use of names that violate ISO/IEC 9899.
Rename endianness macros used in code to use properly-namespaced macros for
portability and cross-hosting compatibility. Add inline functions to perform
common operations with the macros.
