* Fixed a test breaking PyPy. Restored support for Sphinx.
* Made the decorator module more robust when decorating builtin functions
lacking dunder attributes, like `dict.__setitem__`.
* The decorator module was not passing correctly the defaults inside the
`*args` tuple, thanks to Dan Shult for the fix.
* The decorator module was not copying the __module__ attribute anymore.
* Dropped support for Python < 3.5 with a substantial simplification of
the code base (now building a decorator does not require calling "exec").
Added a way to mimic functools.wraps-generated decorators.
