The removal was intentional. In fact it was supposed to be removed from the exported headers in 4.2 but a mistake was made, and this was just now fixed in 4.12. The justification is in the original commit message.

Please re-add this header if possible. If there is a reason that it should not be exposed to userspace and this is a deliberate change, please reassign this bug and I will arrange to bundle it with the collectd source instead.
