Revert all luna temporary annotation changes

Revert all luna temporary annotation changes

Since we don't track APIs in lttng-luna any more, we can simply
ignore changes to the @since annotations. This restores the
temporary changes to their values in the master branch.

This basically reverts the following commits:
