topic: support --rev argument and properly process then as user input

Revisions inputed by the users should be processed using `scmutil.revrange`.
This will take alias into account and allow extensions to monitor the user
inputs.

As a side effect, the '_changetopics' function takes revisions as argument.
make the API clearer.
