merge-actions: have an attribute for narrow safetiness

This allow the core doing narrow filtering to process action without
explicitely listing all possible actions. This is important to make the actions
system more flexible in the future.

after the strip operation. Otherwise remotefilelog has to search every commit in
the repository looking for a valid linkrev every time it's queried, such as
during push.
