Revert needed, since otherwise there is no way to do automatic sorting of includes. Also reverted change to the docs, as leaving it would make incorrect docs. In case of conflicts, includes were sorted according to the coding standards from #3839. This reverts commitb4a9f04f92. This reverts commit5921122960.
