define a structure for object IDs
Many places throughout the code use "unsigned char [20]" to store object IDs (SHA-1 values). This leads to lots of hardcoded numbers throughout the codebase. It also leads to confusion about the purposes of a buffer. Introduce a structure for object IDs. This allows us to obtain the benefits of compile-time checking for misuse. The structure is expected to remain the same size and have the same alignment requirements on all known platforms, compared to the array of unsigned char, although this is not required for correctness.
