8290037: Bindings should clean up after themselves when their weak listeners go out of scope

[hjohn]

This is an initial (incomplete) implementation of 8290037 for evaluation.

If the approach is agreed, I will modify the rest of the *PropertyBase classes which use weak listeners, and add some tests.

I didn't use Cleaner because cleaning up a listener may block.

Ah, I was hoping this was one of the routes without requiring a csr. Perhaps it needs a rethink.
