Use qCountTrailingZeroBits and qCountLeadingZeroBits from qalgorithms.h
instead. Also extended these versions for MSVC. The _bit_scan_* versions
stem from a time before the glorious days of qalgorithms.h. A big
advantage is that these functions can be used on all platforms.

From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

That header defines those constants outside of the math.h include guard,
so if someone #define'd _USE_MATH_DEFINES and #include'd math.h later,
they would get VC++ warnings about constants like M_PI being redefined
with different values (ours have parentheses, VS2010's math.h don't).
Instead, let's define _USE_MATH_DEFINES ourselves so we get the M_*
macros from math.h. That way, we won't redefine them outselves.

Including math.h can pollute the default namespace, and break
some compilers if cmath versions of the method are declared as using.
Switching to C++ math functions also greatly simplifies handling of
float qreal as C++ automatically chooses the right method.
[ChangeLog][QtCore][QtMath] qmath.h no longer includes math.h, so any
sources depending on that indirect inclusion may fail to build.

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Outdated header.LGPL removed (use header.LGPL21 instead)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