Jani Heikkinen 83a5694dc2 Update copyright headers
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Outdated header.LGPL removed (use header.LGPL21 instead)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
