Here comes a new release.

The upstream imaplib2 project is discontinued. That's why I've decided to take
over the maintenance of imaplib2 for offlineimap.

For the use of offlineimap I've applied the pending PRs from imaplib2.  I have
applied another change sent to offlineimap (see OfflineIMAP/offlineimap#623).

However, there are 3 important limitations:

- I intend to maintain imaplib2 for offlineimap only. Everything will take place
  in the offlineimap project. I'll neither package imaplib2 nor maintain any
  "official" repository dedicated to imaplib2. If you want imaplib2 but not
  offlineimap, you should extract the file `offlineimap/bundled_imaplib2.py` from
  the offlineimap repository. Please, send your patches for imaplib2.py to the
  offlineimap project directly.

- Starting from imaplib2 v2.100 (tagged: imaplib2-v2.100) I'm taking the patches
  in the lazy mode. This means that I won't make deep checks/tests of the
  changes.  Hence, the quality and the stability might become a bit more
  fluctuating. For more stability, you might like to only consider the imaplib2
  versions released with the stable versions of offlineimap. Don't expect
  changelogs dedicated to imaplib2. They will be part of the offlineimap
  changelogs.

- All of this only applies to the py2 version of imaplib2. Sadly, offlineimap
  has few chances to be ported on py3 so I don't aim to maintain the py3 version
  of imaplib2.


In this release, offlineimap is learning Happy Eyeballs.
