OfflineIMAP 3.99.16 released

[John Goerzen <jgoerzen@xxxxxxxxxxxx>]

From the changelog:

offlineimap (3.99.16) unstable; urgency=low

  * This is a 4.0 TRACK release, and may be unstable or in flux!
  * When sep was /, the new Maildir support code would recursively try to 
    scan ., resulting in huge paths and an eventual crash.  Fixed with
    a one-line patch to Maildir.py.  Fixes [complete.org #60].
    Closes: #191318.
  * Added some significant debug code to folder/IMAP.py when saving a new
    message with APPEND.  This should make it easier to track down bugs both
    in OfflineIMAP and in mail servers that implement this poorly.
  * Fixed adding of X-OfflineIMAP header when the message starts out with
    no headers.  (This should not generally occur.)  This should help
    with some "invalid literal for long()" problems.
