From Qt 5.7 -> tools & applications are lisenced under GPL v3 with some exceptions, see http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/ Updated license headers to use new GPL-EXCEPT header instead of LGPL21 one (in those files which will be under GPL 3 with exceptions) Change-Id: I42a473ddc97101492a60b9287d90979d9eb35ae1 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com> Reviewed-by: Lars Knoll <lars.knoll@theqtcompany.com>
