A filter needs formats.h iff it uses FILTER_QUERY_FUNC(); since lots of filters have been switched to use something else than FILTER_QUERY_FUNC, they don't need it any more, but removing this header has been forgotten. This commit does this; files with formats.h inclusion went down from 304 to 139 here (it were 449 before the preceding commit). While just at it, also improve the other headers a bit.
