[FIX] function introspection attributes

Introspection attributes on function and methods were originally
prefixed with func_ or im_ e.g. im_class or func_name. For coherence with the
rest of the data model, Python 3 added dunder attributes (__func__,
__code__) and removed the old style, the dunder attributes were
backported to Python 2.6.

Use dunder attributes everywhere we're currently using func_* or im_*
attributes.
