    chunks: cleanup
    
    Define CHUNK(ARRAY).
    
    Move alloc_chunk() to chunk.c - easier to find and easier to debug.
    
    Add free_chunk_contents(), clone_bytes_as_chunk().
    
    Replace same_chunk() with chunk_eq() - presumably like other *eq()
    functions this means contents are equal.
    
    Eliminate str_from_chunk(), use clone_chunk_as_string().
    
    Eliminate clonereplacechunk(), use free_chunk_contents(),
    clone_in_pbs_as_chunk(), clone_bytes_as_chunk() et.al.
