revset: return early when revs is empty
By introducing an early return in _revancestors() when revs is empty,
we make it so inputrev is never None, which simplifies the subsequent
code.

revset: rename 'revsnode' to 'inputrev' in ancestors
We usually use 'node' for variable containing 20 bytes hash. There is nothing
nodish in this variable, so we rename it to "inputrev" as it old the next entry
of the iteration.
