/**
* Basic type definitions.
*
* This header file defines the generic integer types that will be used
* for the implementation of hash functions; it also contains helper
* functions which encode and decode multi-byte integer values, using
* either little-endian or big-endian conventions.
*
* This file contains a compile-time test on the size of a byte
* (the <code>unsigned char</code> C type). If bytes are not octets,
* i.e. if they do not have a size of exactly 8 bits, then compilation
* is aborted. Architectures where bytes are not octets are relatively
* rare, even in the embedded devices market. We forbid non-octet bytes
* because there is no clear convention on how octet streams are encoded
* on such systems.
