  [Bug #1613651] Document socket.recv_into, socket.recvfrom_into

  Also, the text for recvfrom told you to read recv() for an explanation of the
  'flags' argument, but recv() just pointed you at the man page.  Copied the
  man-page text to recvfrom(), recvfrom_into, recv_into to avoid the pointless
  redirection.

  [Apply length-checking.diff from bug #1599254]

  Add length checking to single-file mailbox formats: before doing a
  flush() on a mailbox, seek to the end and verify its length is
  unchanged, raising ExternalClashError if the file's length has
  changed.

  This fix avoids potential data loss if some other process appends to
  the mailbox file after the table of contents has been generated;
  instead of overwriting the modified file, you'll get the exception.

  I also noticed that the self._lookup() call in self.flush() wasn't
  necessary (everything that sets self._pending to True also calls
  self.lookup()), and replaced it by an assertion.

  2.5 backport candidate.

  exception.  (<crossing fingers for the buildbots>)
