    Also reject requests to allocate negative sized amounts of memory
    
    Since the API is defined with size as a signed int, deal with it.

commit 2da1bcb656febdab9345f1fec31c974fd7b409bc

    Ensure ARRAYofARRAY8 pointers are initialized to NULL
    
    Use calloc for the array of pointers to ensure pointers are cleared out
    so we don't try to free garbage if XdmcpDisposeARRAYofARRAY8 is called
    before the caller sets them to valid pointers.

    Ensure ARRAY* structs are zero'ed out when oversize values are passed
    
    Previous fix missed a case in which we returned failure, but didn't
    fill in the data pointer & size values.
