Code freeze break request for Evolution-Data-Server

[Matthew Barnes <mbarnes redhat com>]

Having spent the day debugging frequent crashes in Evolution 3.3.92, I
now have a series of commits for the IMAPX backend which makes Evolution
sufficiently stable again for 3.4.0.

Details and the patches are here:
https://bugzilla.gnome.org/show_bug.cgi?id=672717

I'd like to get them in before Monday's release.  All of them.
