- Fix declaration of functions wrt TSDLLEXPORT consistency
- Empty structs need to be created with '{ 0 }' syntax.
- Alignment sentinels have to use uint64 instead of a struct
with a 0-size member
- Add some more ORDER BY clauses in the tests to constrain
the order of results
- Add ANALYZE after running compression in
transparent-decompression test
