Compilation and link times in CPU seconds with GCC 7, using precompiled
headers (not including moc, rcc, uic, etc. steps or headersclean):
Before After
Debug -O0 198,1 180,3
Debug -Og 240,7 229,2
Release -O3 267,1 249,2
Release LTO 239,4 229,8
QtCore required a little manual adjusting because some files are
bootstrapped into moc itself and into qmake.

Move instead of copy the bezierCurves and tcbPoints
containers when updating 'config' in setType_helper().
In Qt 5, we still have the unsharable container
issue which causes code for deep copies to be
emitted for most copy operations.
A move is always just re-seating a pointer.

The relevant easing curves all start out fast and end stationery; so
it's at the *end* that they attain zero "velocity", so they're
decelerating *to* zero, not from it.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

The copy constructor used the default Private constructor,
followed by the application of the compiler-generated
copy assignment operator, and finally replaced the config
member with a copy of itself.
This is needlessly inefficient.
Worse: it's incorrect: if config->copy() throws, then
*d_ptr is leaked.
Solution: implement the copy constructor for Private,
and use it in the copy constructor of the public class.
Effect: everything that can throw now prevents the new
Private class from being created, and the compiler ends
up cleaning up after us.

QEasingCurve internally holds the spline data in a
QVector<QPointF>. For the return from cubicBezierSpline(),
the vector is transformed into a QList<QPointF>.
This involves copying, and into an inefficient (for QPointF
payloads) container at that, so deprecate cubicBezierSpline()
in favour of a new toCubicSpline() returning the QVector
directly.

For -O2 gcc activates -fstrict-aliasing. As a result the compiler is
allowed to assume that pt[1]=px[1]/3+B1 does not affect t.
Therefore the result of _fast_cbrt() was always 0.
Using a union for casting avoids this issue.
For more details see:
http://labs.qt.nokia.com/2011/06/10/type-punning-and-strict-aliasing

I added the possibilty to define Bezier/TCB splines and use them
as custom easing curves.
Note:
Splines have a parametric definition. This means we have a
function/polynom of t that evalutes to x and y. x/y = f(t).
For our purpose we actually need the function y = f(x).
So as a first step we have to solve the solution x = f(t) for a given
t and then in a second step we evaluate y = f(t).
f(t) is a cubic polynom so we use cardanos formula to solve this equation
directly.
For the casus irreducibilis we need 3 functions that are a combination of
arcos and cos. Instead of evaluating arcos and cos we approximate these
functions directly.
TCB splines are converted into the corresponding cubic bezier spline.
