Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
