Issue 2408: remove the _types module
It was only used as a helper in types.py to access types (GetSetDescriptorType and MemberDescriptorType),
when they can easily be obtained with python code.
These expressions even work with Jython.
I don't know what the future of the types module is; (cf. discussion in http://bugs.python.org/issue1605 )
at least this change makes it simpler.

- Issue #2550: The approach used by client/server code for obtaining ports
to listen on in network-oriented tests has been refined in an effort to
facilitate running multiple instances of the entire regression test suite
in parallel without issue. test_support.bind_port() has been fixed such
that it will always return a unique port -- which wasn't always the case
with the previous implementation, especially if socket options had been
set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
new implementation of bind_port() will actually raise an exception if it
is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
SO_REUSEPORT socket option set. Furthermore, if available, bind_port()
will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
This currently only applies to Windows. This option prevents any other
sockets from binding to the host/port we've bound to, thus removing the
possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
that occurs when a second SOCK_STREAM socket binds and accepts to a
host/port that's already been bound by another socket. The optional
preferred port parameter to bind_port() has been removed. Under no
circumstances should tests be hard coding ports!
test_support.find_unused_port() has also been introduced, which will pass
a temporary socket object to bind_port() in order to obtain an unused port.
The temporary socket object is then closed and deleted, and the port is
returned. This method should only be used for obtaining an unused port
in order to pass to an external program (i.e. the -accept [port] argument
to openssl's s_server mode) or as a parameter to a server-oriented class
that doesn't give you direct access to the underlying socket used.
Finally, test_support.HOST has been introduced, which should be used for
the host argument of any relevant socket calls (i.e. bind and connect).
The following tests were updated to following the new conventions:
test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
test_poplib, test_ftplib, test_telnetlib, test_socketserver,
test_asynchat and test_socket_ssl.
It is now possible for multiple instances of the regression test suite to
run in parallel without issue.

No detailed change log; just check out the change log for the py3k-pep3137
branch. The most obvious changes:
- str8 renamed to bytes (PyString at the C level);
- bytes renamed to buffer (PyBytes at the C level);
- PyString and PyUnicode are no longer compatible.
I.e. we now have an immutable bytes type and a mutable bytes type.
The behavior of PyString was modified quite a bit, to make it more
bytes-like. Some changes are still on the to-do list.

In response to this SF bug:
[ 1752723 ] email.message_from_string: initial line gets discarded
I added a test to assert that when the first line of text passed to
message_from_string() contains a leading space, the message ends up with the
appropriate FirstHeaderLineIsContinuationDefect on its defects list.
The bug is invalid.

Avoid exception if there's a stray directory inside a Maildir folder.
The Maildir specification doesn't seem to say anything about this
situation, and it can happen if you're keeping a Maildir mailbox in
Subversion (.svn directories) or some similar system. The patch just
ignores directories in the cur/, new/, tmp/ folders.
