smtp: add the class to verify the certificate of the SMTP server for STARTTLS

Original "smtplib.SMTP" has no route to pass "ca_certs" and
"cert_reqs" arguments to underlying SSL socket creation. This causes
that "getpeercert()" on SSL socket returns empty dict, so the peer
certificate for STARTTLS can't be verified.

This patch introduces the "STARTTLS" class derived from "smtplib.SMTP"
to pass "ca_certs" and "cert_reqs" arguments to underlying SSL socket
creation.

Almost all code of "starttls()" in this class is imported from
"smtplib.SMTP" of Python 2.7.3, but it differs from original code in
points below:

  - "self.ehlo_or_helo_if_needed()" invocation is omitted, because:

    - "ehlo_or_helo_if_needed()" is available with Python 2.6 or later, and
    - "ehlo()" is explicitly invoked in "mercurial.mail._smtp()"

  - "if not _have_ssl:" check is omitted, because:

    - "_have_ssl" is available with Python 2.6 or later, and
    - same checking is done in "mercurial.sslutil.ssl_wrap_socket()"

  - "ssl.wrap_socket()" is replaced by "sslutil.ssl_wrap_socket()" for
    compatibility between Python versions

  - use "sock.recv()" also as "sock.read()", if "sock" doesn't have
    "read()" method

    with Python 2.5.x or earlier, "sslutil.ssl_wrap_socket()" returns
    "httplib.FakeSocket"-ed object, and it doesn't have "read()"
    method, which is invoked via "smtplib.SSLFakeFile".
