[issue14065] Element should support cyclic GC

[Eli Bendersky]

Find attached a patch.

Added cyclic GC support to Element objects. Also added tests that verify that cycles involving Element objects are being collected.

I'd really appreciate a review on this, since this is the first time I have to explicitly deal with cyclic GC from C extensions.
