Issue #17463: Fix test discovery for test_pdb.py
Documentation corrections for unittest.mock
#10050 - Document DeprecationWarnings for URLopener and FancyURLopener (msg172874 )
#17476: make allmethods actually return all methods.

This fixes a regression relative to Python2.  (In 2, methods on a class were
unbound methods and matched the inspect queries being done, in 3 they are just
functions and so were missed).

This is an undocumented function that pydoc itself does not use, but
I found that numpy at least uses it in its documentation generator.
