utility: add a function to prompt user to choose a revision

This patch adds a utility function to interactively prompt user to choose a
revision to proceed in cases when there are multiple revisions which are
candidates.

The function will be used in `hg evolve`, `hg next`, `hg prev` etc. If user
feedback will be good, I plan to move it to core and use it at more possible
places.
