dialyzer: Fix a bug in the translation of forms to types
A bug is fixed, but there are more problems.
Modify erl_types.erl like this:
-define(EXPAND_LIMIT, 500).
and bogus warnings are output (again).
Callbacks and specs are compared (subtype) in dialyzer_behaviour. If
they are expanded to different depths, then invalid warnings can be
generated.
