[dialyzer] Re-work the handling of opaque types
It is now OK to inspect and modify the internals of opaque types within
the scope of the module.
The contracts are used for decorating types with opaqueness when it is
harmless to do so. The opaqueness is propagated by the typesig module
and also by the dataflow module.
A lot of details have been fixed or updated. In particular the modules
erl_types and erl_bif_types have been modified extensively.
The version in vsn.mk has been updated to 2.7. The reason is a
modification of #opaque{} in erl_types.
Dialyzer seems to be about five percent slower than it used to be.
