Update to match semantics of new imaplib2

Browse Source 
The biggest change here is that imapobj.untagged_responses is no
longer a dictionary, but a list. To access it, I use the semi-private
_get_untagged_response method.

* offlineimap/folder/IMAP.py (IMAPFolder.quickchanged,
  IMAPFolder.cachemessagelist): imaplib2 now explicitly removes its
  EXISTS response on select(), so instead we use the return values from
  select() to get the number of messages.

* offlineimap/imapserver.py (UsefulIMAPMixIn.select): imaplib2 now
  stores untagged_responses for different mailboxes, which confuses us
  because it seems like our mailboxes are "still" in read-only mode when
  we just re-opened them.  Additionally, we have to return the value
  from imaplib2's select() so that the above thing works.

* offlineimap/imapserver.py (UsefulIMAPMixIn._mesg): imaplib2 now
  calls _mesg with the name of a thread, so we display this
  information in debug output. This requires a corresponding change to
  imaplibutil.new_mesg.

* offlineimap/imaplibutil.py: We override IMAP4_SSL.open, whose
  default arguments have changed, so update the default arguments. We
  also subclass imaplib.IMAP4 in a few different places, which now
  relies on having a read_fd file descriptor to poll on.
