bpo-28533: Remove asyncore, asynchat, smtpd modules (GH-29521)
Remove the asyncore and asynchat modules, deprecated in Python
3.6: use the asyncio module instead.

Remove the smtpd module, deprecated in Python 3.6: the aiosmtpd
module can be used instead, it is based on asyncio.

* Remove asyncore, asynchat and smtpd documentation
* Remove test_asyncore, test_asynchat and test_smtpd
* Rename Lib/asynchat.py to Lib/test/support/_asynchat.py
* Rename Lib/asyncore.py to Lib/test/support/_asyncore.py
* Rename Lib/smtpd.py to Lib/test/support/_smtpd.py
* Remove DeprecationWarning from private _asyncore, _asynchat and
  _smtpd modules
* _smtpd: remove deprecated properties

bpo-44498: Issue a deprecation warning on asynchat, asyncore and smtpd import (#26882)
* Issue a deprecation warning on smtpd import

* Also issue DeprecationWarnings for asynchat and asyncore

* Fix some tests

* test___all__ requires the word 'module' or 'package' in the deprecation
  warning text, so add those to smtpd, asynchat, and asyncore.
* In test_support, use pprint now instead of asyncore as the landmark.

* Add What's New

* Use ..deprecated::

* Use ..deprecated::

* Update Lib/smtpd.py

* Update Doc/library/smtpd.rst

* Import async{hat,ore} after the DeprecationWarning for this module

Remove binding of captured exceptions when not used to reduce the chances of creating cycles (GH-17246)
Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles.

See for example GH-13135

    Moved all of the capture_server socket setup code into the try block
    so that the event gets set if a failure occurs during server setup
    (otherwise the test will block forever).  Changed to let the OS assign
    the server port number, and client side of test waits for port number
    assignment before proceeding. The test data in DispatcherWithSendTests
    is also sent in multiple send() calls instead of one to make sure this
    works properly. [GSoC - Alan McIntyre]

Tim Peters 6fd7120616 Fix from the Madusa mailing list:
http://groups.yahoo.com/group/medusa/message/333

It's clear that Medusa should not be checking for an empty buffer
via "buf is ''".  The patch merely changes "is" to "==".  However,
there's a mystery here all the same:  Python attempts to store null
strings uniquely, so it's unclear why "buf is ''" ever returned
false when buf actually was empty.  *Some* string operations produce
non-unique null strings, e.g.

>>> "abc"*0 is "abc"*0
0
>>>

but they're rare, and I don't see any such operations in asynchat.
