Make it easier to run and test Python on systems with restrict crypto policies:
* add requires_hashdigest to test.support to check if a hash digest algorithm is available and working
* avoid MD5 in test_hmac
* replace MD5 with SHA256 in test_tarfile
* mark network tests that require MD5 for MD5-based digest auth or CRAM-MD5

Two kind of mistakes:
1. Missed space. After concatenating there is no space between words.
2. Missed comma. Causes unintentional concatenating in a list of strings.
* Make sure that when some of the tests in test_smtplib fail, the allocated threads
and sockets are not leaked.
* Use support.join_thread() instead of thread.join() to avoid infinite blocks.
Some methods of the SMTP class use mutable default arguments. Specially
`send_message` is affected as it mutates one of the args by appending items
to it, which has side effects on further calls.
Enable and fix SMTPUTF8SimTests in test_smtplib.
The tests for SMTPUTF8SimTests in test_smtplib.py were not actually
being run because test_smtplib was still using the 'test_main' pattern,
and the class was never added to test_main.
Additionally, one of the tests needed to be moved to the non-UTF8 server
class because it relies on the server not being UTF-8 compatible (and it
had a bug in in).
test.support.HOST should be "localhost" as it was in the past. See the bpo-29639.
Tests that need the IP address should use HOSTv4 (added) or the existing HOSTv6 constant.
This changes the definition and fixes tests that needed updating to deal with HOST being
the hostname rather than the hardcoded IP address.
This is only the first step in addressing https://bugs.python.org/issue29639.
The auth method tests simply weren't adequate because of the fact that
smtpd doesn't support authentication. I borrowed some of Milan's
code for that from issue #21935 and added it to the smtplib tests.
Also discovered that the direct test for the 'auth' method wasn't actually
testing anything and fixed it.
The fix makes the new authobject mechanism work the way it is
documented...the problem was that wasn't checking for a 334 return code
if an initial-response was provided, which works fine for auth plain
and cram-md5, but not for auth login.
Without this reset, starttls would fail if a connect/starttls was done after a
quit, because smtplib assumed the existing value of emspt_features was
accurate, but it gets reset when starttls completes (and the new value does
not contain the starttls capability, since tls is already started at that
point). (There may be additional places where this lack of reset was an
issue as well.)
Patch by Milan Oberkirch.
Normally an SMTP server will return an error, and smtplib will then issue an
RSET to return the connection to the known starting state. Some servers,
however, disconnect after issuing certain errors. When we issue the RSET,
this would result in raising an SMTPServerDisconnected error, *instead* of
returning the error code the user of the library was expecting. This fix
makes the internal RSET calls ignore the disconnection so that the error code
is returned. The user of the library will then get the SMTPServerDisconnected
error the next time they try to talk to the server.

This is a partial fix to the issue of servers disconnecting unexpectedly; in
this case the 421 says they are disconnecting, so we close the socket and
return the 421 in the appropriate error context.
Original patch by Mark Sapiro, updated by Kushal Das, with additional
tests by me.

smtpd now handles EHLO and has infrastructure for extended smtp command mode.
The SIZE extension is also implemented. In order to support parameters on
MAIL FROM, the RFC 5322 parser from the email package is used to parse the
address "token".
Logging subclasses things and overrides __init__, so it was necessary to
update those __init__ functions in the logging tests to make the logging tests
pass.
The original suggestion and patch were by Alberto Trevino. Juhana Jauhiainen
added the --size argument and SIZE parameter support. Michele Orrù improved
the patch and added more tests. Dan Boswell conditionalized various bits of
code on whether or not we are in HELO or EHLO mode, as well as some other
improvements and tests. I finalized the patch and added the address parsing.
