@Add first cut of OSSP ui64, a new (sub-)library which allows us to
perform 64-bit unsigned integer arithmetic in a portable way without
requiring the machine to support C99's 64-bit type "unsigned long long".
Basically a ui64_t is an 8 byte array of "unsigned char" elements and
hence the library internally stores 64-bit values as 8 digits to the
base 2^8 and also performs the mathematical operations this way.
