rejects builtin types with not defined __new__.
Added tests for non-pickleable types.

Patch started by Stéphane Wirtel.

It now has slightly better rationale and a less awkward wording in the
explanation.

Inspired by a report of a neither/or conflict by 'animalize' on docs@.

Use time.monotonic or time.time instead of time.clock.

failure when the test is ran the second time.

The root attribute was set in parent class in setUpClass and then
overridded in child class in tearDownClass.

This avoids possible buffer overreads when int(), float(), compile(), exec()
and eval() are passed bytes-like objects. Similar code is removed from the
complex() constructor, where it was not reachable.

Patch by John Leitch, Serhiy Storchaka and Martin Panter.

Implementation by Antoine Pitrou.

This changes the main documentation, doc strings, source code comments, and a
couple error messages in the test suite. In some cases the word was removed
or edited some other way to fix the grammar.

Clarify message and expected action for beginners.
Guard against astral chars in path incorporated in message.

This restores details lost in revision 097f4fda61a4 (since Python 3.3,
related to the new OSError subclasses). Further additions:

* Markup for attributes and constructor signature
* Explain "winerror" and "filename2"
* Extend test to check for filename2 defaulting to None
* Clarify that the constructor can return a subclass

I have intentionally left out any details of allowing more than five
arguments, or how the "args" attribute is set for four or more arguments.
These details seem to be dependent on the Python version and platform.

rather than from elsewhere on PATH.

This removes the need to add externals/tcltk[64]/bin to PATH to be able
to import tkinter.  Also documents the necessity for the DLLs to be
on PATH or in python.exe's directory.
