typelib: Fix invalid alignment assumptions

Browse Source 
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.
