evolve: distinct between '--all' and '--all --any'
Before this patch, evolve --all implied evolve --all --any. With this patch
evolve --all evolves all the aspiring descendants of the parent of the working
copy. evolve --all --any does what evolve --all did before: evolving all the
troubles in the repo.
We add anew function _aspiringdescendant for this purpose

rework refactor _aspiringchildren by introducing _possibledestination
This allows us to reuse some of the logic for evolve from _aspiringchildren
for the new implementation of evolve --all.
The logic is also better as some previously selected changesets may not actually
evolve on the target, and some changesets that does not would not.
