[Development] Dropping VS 2012 in Qt 5.7

Hi,
as Maintainer of the Windows Embedded Compact Platforms it makes sense
to look forward and agree with dropping the platform in favor to support
new features. Also Microsoft seems to abandon this platform, so Qt needs
todo the same for going forward. But we will still support 5.6 as LTS
Version with WEC7 and WEC2013.
I will have a look at those patches which went in 5.7.
The OpenSSL patch seems to be no release blocker for 5.6.0 as well as
the sqlite build problem can only be seen if -qt-sql-sqlite is getting
passed to configure. If nothing is specified, it defaults to plugin and
does not break the build.
The rest I will have a look.
Thank you
Andy
