Previously, we would divide by zero in BezierEase::findTForX if factorT3
was zero when solving the cubic equation.
This change fixes the problem by adding solutions for the special cases
where the cubic equation can be reduced to a quadratic or linear
equation.
This change also adds tests that cover cases where the equation becomes
quadratic, linear or invalid.

This system is no longer in the CI rotation and we haven't had reports
of the same issues happening on later versions. Either the issues have
since been fixed or they were never an issue in Qt in the first place.
This commit has the additional benefit of getting rid of the following
shell error when qmake was run:
sh: line 0: [: =: unary operator expected
as /etc/lsb-release hasn't contained DISTRIB_CODENAME for some time and
proper quoting was never implemented (not even qtcpsocket.pro).

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Outdated header.LGPL removed (use header.LGPL21 instead)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

Previously, this failed because QEasingCurveFunction only had a linear
behavior.
The fix is to change that and let QEasingCurveFunction handle
any of the simple "non-parametric easing" functions.

Qt 5.0 beta requires changing the default to the 5.0 API, disabling

compatibility API too, so turn it back on.

The move constructor sets other.d_ptr to zero. This is safe, because
after being moved from, the object is left in a state in which it
can be safely destroyed (delete nullptr is a no-op).
It cannot meaningfully be used anymore (most members will crash with
a nullptr dereference), but in most cases, the moved-from object
cannot be accessed anyway (not a named object), and if a named object
is moved from, it must have been through explicit std::move(), as in
the test case.
The STL makes better guarantees (moved-from containers are .empty()),
but I don't think it's worth introducing a null state into
QEasingCurve just for supporting a use-case that should be
considered a bug anyway.
