    Make ImageEncodings unsigned
    
    Starts at 0 and increments to count encodings - should never go negative.
    
    Fixes clang warnings:
    
    xvinfo.c:184:31: warning: implicit conversion changes signedness: 'int' to
          'unsigned int' [-Wsign-conversion]
                    if (nencode - ImageEncodings) {
                                ~ ^~~~~~~~~~~~~~
    
    xvinfo.c:186:39: warning: implicit conversion changes signedness: 'int' to
          'unsigned int' [-Wsign-conversion]
                                nencode - ImageEncodings);
                                        ~ ^~~~~~~~~~~~~~

    Convert sprintf call to use snprintf
    
    Should be impossible to overflow with previous sprintf code, but
    still safer to avoid bugs if something changes in the future.
