8095c33bcd Use qRadiansToDegrees() and qDegreesToRadians() more widely
Especially in examples, where we should show off our convenience
functions, prefer calling these functions over doing arithmetic with
M_PI (or approximations thereto) and 180 (give or take simple
factors).  This incidentally documents what's going on, just by the
name of the function used (and reveals at least one place where
variables were misnamed; the return from atan is in radians, *not*
degrees).

9e49778380 Fix/adapt the uses of {to,set,from}Time_t in the qtbase source code
Move those to the equivalent {to,set,from}SecsSinceEpoch(), except for
the cases that did QDateTime::currentDateTime{,Utc}().toTime_t. Those
are best implemented with QDateTime::currentSecsSinceEpoch().

515e802ae2 Use C++ <cmath> instead of <math.h>
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.

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Outdated header.LGPL removed (use header.LGPL21 instead)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

3b0c2b7c1b Examples: Add Q_DECL_OVERRIDE to overridden functions
Q_DECL_OVERRIDE (which expands to 'override' for supported compiler)
helps to declare the intent (that it is an overridden function) and
force compilation error when there is no such virtual function in the
base class.
The examples should show the best practice of having it, as it may save
the programmer quite some time in case of change of API or typo in the
function name or arguments.

This change was done automatically with
clang-modernize -add-override -override-macros

And fixed MSVC compilation by removing inline for TorrentViewDelegate::paint

b11317a643 Whitespace cleanup: remove trailing whitespace
Remove all trailing whitespace from the following list of files:
*.cpp *.h *.conf *.qdoc *.pro *.pri *.mm *.rc *.pl *.qps *.xpm *.txt *README
excluding 3rdparty, test-data and auto generated code.

Note A): the only non 3rdparty c++-files that still
have trailing whitespace after this change are:
* src/corelib/codecs/cp949codetbl_p.h
* src/corelib/codecs/qjpunicode.cpp
* src/corelib/codecs/qbig5codec.cpp
* src/corelib/xml/qxmlstream_p.h
* src/tools/qdoc/qmlparser/qqmljsgrammar.cpp
* src/tools/uic/ui4.cpp
* tests/auto/other/qtokenautomaton/tokenizers/*
* tests/benchmarks/corelib/tools/qstring/data.cpp
* util/lexgen/tokenizer.cpp

Note B): in about 30 files some overlapping 'leading tab' and
'TAB character in non-leading whitespace' issues have been fixed
to make the sanity bot happy. Plus some general ws-fixes here
and there as asked for during review.

aeb036ed87 centralize and fixup example sources install targets
it's confusing for the users if the examples' project files contain code
to install their own sources. also, this constitutes an enormous code
duplication, and lots of mistakes. consequently, automate it.

more or less as a side effect, this also removes the entirely meaningless
target installs in subdirs projects.

43325a23f3 Delete the QVariant ctors taking global Qt enum values.
They have unexpected results in Qt 5 (the Qt::GlobalColor one works
as expected in Qt 4, but was removed in Qt 5):

 QVariant v = QVariant(Qt::red);
 qDebug() << v; // QVariant(int, 7)
 v = Qt::red;
 qDebug() << v; // QVariant(int, 7)

The correct way is to use:

 QVariant v = QVariant::fromValue(QColor(Qt::red));

The deleted constructors are the ones for which there is a class
with an implicit constructor taking the enum, and that class is
a built-in metatype.

QLocale::Language and QKeySequence::StandardKey would also fit
the description, but I can't include the header for QKeySequence
as it is in QtGui, and I don't want to include the qlocale header
in qvariant.h. Putting a QLocale::Language is probably very
uncommon anyway.

The QTextFormat test is doing the wrong thing, but the result isn't
being tested. Added new tests which fail before the patch.
