the last one ( sqlite3_trace ) is actually a pretty bad conversion,
changing a pointer to a u32 and vice versa; but it is only an internal
function so maybe it doesn't matter.
The rest are because SQLITE_TRANSIENT : SQLITE_DYNAMIC aren't just simple
values, but are function pointers with different signatures...
