evolution-data-server and a new Google HTTP restriction

[Milan Crha <mcrha redhat com>]

        Hello,
Andre asked me to give a heads-up about an issue of repeated password 
prompts for Google calendars configured through Online Accounts. The 
problem was that Google changed some policy and it is using a new HTTP
restriction. That's reported at [1], where you can see also more 
details.

The fix landed for evolution-data-server 3.12.6 (current stable) and 
evolution-data-server 3.13.6 (to be released development version).
Frank Dana also attached a backport of the fix for 3.10.4 at [2].

I suggest to either update to the recent stable version with the fix 
included or use the backported version for 3.10.4, thus you can avoid 
headache to your users and bug masters.

        Bye,
        Milan
