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.
The deprecation include manual creation of SSLSocket and certfile/keyfile
(or similar) in ftplib, httplib, imaplib, smtplib, poplib and urllib.
ssl.wrap_socket() is not marked as deprecated yet.
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.

requires them. Disable executable bits and shebang lines in test and
benchmark files in order to prevent using a random system python, and in
source files of modules which don't provide command line interface. Fixed
shebang lines in the unittestgui and checkpip scripts.

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.

tests by me.

tests by me.
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.
There are doubtless other debug messages in smtplib that would trigger an
error if they were tested, but this fixes the things we do now test,
which is good enough for now.
