struct packed: add fallback byte array implementation, use gcc_struct on Windows, unit tests
https://sourceware.org/bugzilla/show_bug.cgi?id=29373
- Windows hosts need attribute gcc_struct.
- attribute gcc_struct seemingly doesn't work with Clang, so add a
fallback standard-conforming implementation based on arrays.
- add unit tests to make sure both implementations behave the same
way.
- add more relational operators while at it.
