    typelib: Fix invalid alignment assumptions
    
    The current source has invalid assumptions about structure alignment
    that break on platforms like m68k where 32-bit integers are aligned to
    16-bit only. Fix this by introducing explicit structure padding for
    32-bit quantities following odd numbers of 16-bit quantities and
    structure trail padding, to make the binary representation generated
    by the compiler match the text of the specification exactly.
