Reduce pylint complaints about Util

Fix up UniqueList - remves a Py2-era method and correct args on others;
  add a __repr__ which does the uniquing.
Add "we know what we're doing" pylint comments on apparent redefinitions
  of builtins and globals that the type tests and type converters do.
Add some more pylint comments on "local" (rather than top of file) imports.
Remove WindowsError reference (necessitated changing some tool code
  as well) - partial fix for #3939, WinodwsError is no longer distinct
Simplified semi-deepcopy stuff (and quieted complaints)

Add class docstrings and fixup some docstrings.

AddMethod examples had reversed arguments - now rendered as a
doctest, and actually works.  Fixed up other examples to (mostly)
be doctest as well.
