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Outdated header.LGPL removed (use header.LGPL21 instead)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

When calling intersect() on a large (1000000 items) QSet, with a small
(1000 items) QSet as the argument, the function takes signifcantly
longer than when the operand and the argument are reversed. This is
because the operand set is always iterated over in its entirety.
This patch changes intersect() to iterate over the smaller set. This
reduces the large operand scenario's benchmark to ~0.000063
milliseconds, compared to the current ~134 milliseconds:
1000000.intersect(1000) = empty: 0.000063 (was 134)
1000.intersect(1000000) = empty: 0.000039 (was 0.000036)
1000000.intersect(1000) = 500: 0.10 vs (was 130)
1000.intersect(1000000) = 500: 0.023 vs (was 0.093)
1000000.intersect(1000) = 1000: 0.20 vs (was 139)
1000.intersect(1000000) = 1000: 0.017 vs (was 0.016)
