_addset: add a __len__ method

Back in the time where repo.revs(...) returned a list, calling `len(...)` on the
result was quite common. We reinstall this on _addset.

There is absolutely no easy way to test this from the command line. The commands
using this in the evolve extension will eventually land into core.
