Bug 19410: (follow-up) Add reserved params definitions

This patch re-adds some parameters I left out during some rebasing tasks
and ended up on a separate patchset (bug 18731).

The introduced parameters definitions are only used on endpoint definitions
that implement (at least) pagination. No need to test them here but easier
adding them here than on a patch implementing a new enpoint, which would become
a dependency for other endpoints.
