Make UnownedPtr and RetainPtr more similar to each other.

The remaining difference is that UnownedPtr<T> has operator=(T*),
which prevents one test from compiling until it is removed (which
will create a lot of code churn).

-- add new assignment operators.
-- add new tests and simplify existing ones.
-- add some "noexcepts" and "defaults"
-- template/untemplate some methods.
-- add MakeUnowned() helper.
