8d32204592 QStringRef: fix trimmed() returning null strings on empty input
The QString API symmetry test strikes again, showing that this is
inconsistent with both QString and QByteArray, which both return empty
for empty inputs.

The fix actually makes the implementation simpler.

Extend the QStringRef test to cover null inputs, too. I can't merge
the trimmed() test in the API symmetry test until everything is
actually consistent.

[ChangeLog][QtCore][QStringRef] trimmed() now returns an empty
string-ref for an empty input. Before, it would return a null one.

7849aa6e96 Windows QPA: Add native menus
Add simple Win32-API based menus (not owner-drawn).

Native menus are implemented using Win32 API and are simpler than
QMenu-based menus in for example that they do allow for placing widgets on
them or changing properties like fonts and do not provide hover signals.
They are mainly intended for Qt Quick. By default, they will be used if the
application is not an instance of QApplication or for Qt Quick Controls
2 applications.

In addition, the command line option -platform windows:menus=native
will unconditionally activate them and -platform windows:menus=no
turns them off.

940b36850d QLocaleData: remove unused bool *overflow arguments
... from bytearrayToDouble() and bytearrayToLongLong()

The only user, QIntValidator, always checked them in conjunction with

no point in carrying both.

We can bring this code back with QParsedNumber, when it will not cost
anything anymore. I actually was hoping that the overflow argument
would inform the design of QParsedNumber, but it turned out to be
unused, leading to this commit instead.

629422607f QCompletionEngine: avoid a node allocation on lookup
In matchHint() and lookupCache(), instead of checking for the
existence of 'parent' in 'cache', a new entry was created, if
needed.

However, the remainders of the functions could only fail in
that case, so don't allocate an empty map node here at all.
Wherever something sensible is added to the cache, there will
have to be an insertion of the same node anyway, so there's
no point doing that work here.

Allows to mark these functions const.

Also passed the QString argument by const-reference instead
of by value.

70d8460fc2 QNAM: delay SSL initialization

(Open)SSL initialization; this is apparently done by QSslConfiguration's
default constructor and we have several classes including QSslConfiguration

There are different problems reported because of this, from crashes
(a broken OpenSSL on Windows) to long initialization times, which is
not acceptable if no 'https' request was actually executed.

with smart-pointers and delays (Open)SSL initialization.

Was uncovered by tests for QLatin1String::startsWith(), but added a

than desired, due to the lack of QUtf8String.

5677b70eee QThread: terminate on exceptions leaving run()
Align ourselves to the Standard Library and call std::terminate if an
exception leaves the thread entry point (that is, run()).

On platforms using pthreads, thread cancellation needs to be taken in
special consideration, since it looks like it was supported before.

On Glibc, and when using C++, pthread_cancel and pthread_exit are
implemented by throwing a special kind of exception that can be caught,
but must always be rethrown. That exception is then used to activate the
cancellation clean-up handlers. (This is non-Standard C++ behavior.)

So: mimic what libstdc++'s std::thread does to support Glibc's pthread
cancellation.

At this time, it looks like libc++ has no support for this, and when
used in combination with Glibc a thread cancellation results in a crash
(also because it does not seem to terminate() when exceptions leave the
thread).

[ChangeLog][QtCore][QThread] An exception escaping from QThread::run()
will now result in immediate and abnormal program termination. The same
applies if an exception leaves a slot connected directly to the
QThread::started() or QThread::finished() signals.

164392548e Disentangle string-related headers
It's starting to hinder QStringView development
(QString::append(QStringView), e.g.).

- qbytearray.h includes qstring.h, but is included by qstring.h
  -> remove qstring.h include from qbytearray.h

- the QStringLiteral definition is used from both qstring.h and
  qstringview.h
  -> extract into its own header, move QStringViewLiteral definition
     there, too

- the qCompareStrings(), qConvertTo*() functions are used by QString
  and QStringView
  -> also extract into own header, included from qstring.h and
     qstringview.h

- QStringView::toString() depends on QString, which depends on
  QStringView
  -> move QStringView::toString() definition to qstring.h, after the
     definition of QString
  -> move qstringview.h up to all the other includes in qstring.h

This is starting to look like a DAG again, and allows to remove the
unholy

  #ifndef QSTRING_H
  #  include <qstring.h>
  #endif

hack from qstringview.h.

[ChangeLog][Potentially Source-Incompatible Changes][QByteArray]
qbytearray.h no longer includes qstring.h. In particular, this means
that in order to use QStringBuilder with QByteArray, you need to
include both qbytearray.h and qstring.h now (or <QByteArray> and
<QString>, resp.).

597d4ff796 QThread: add static create function
In the spirit of std::thread, which takes a function to call and its
parameters, and runs it in a new thread. Since the user might want to
connect to signals, move QObjects into the new thread, etc., the new
thread is not immediately started.

Although technically all of this _should_ be implementable in pure
C++11, there is nothing in the Standard to help us not reinvent all the
plumbing: packing the decay'd parameters, storing them, invoking the
function over the parameters (honoring INVOKE/std::invoke semantics).
std::function does not do the job, as it's copiable and therefore does
not support move-only functors; std::bind does not have INVOKE
semantics.

I certainly do not want to reimplement all the required facilities
inside of Qt. Therefore, the full blown implementation requires C++17
(std::invoke).

In order to make this useful also in pre-C++17, there are two additional
implementations (C++11 and C++14) that support just a callable, without
any arguments passed to it. The C++11 implementation makes use of a
class to store and call the callable (even move-only ones); basically,
it's what a closure type for a C++14 lambda would look like.

An alternative implementation could've used some of the existing
facilities inside QObject::connect implementation that store a functor
(for the connect() overload connecting to free functions), namely:
the QtPrivate::QFunctorSlotObject class. However:

* QFunctorSlotObject does not support move-only callables (see
QTBUG-60339);
* QFunctorSlotObject itself is not a callable (apparently by design),
and requires to be wrapped in a lambda that calls call() on it;
* the moment QTBUG-60339 is solved, we'd need the same handwritten
closure to keep QFunctorSlotObject working with move-only callabes.

So: just use the handwritten one.

The C++14 implementation is a simplified version of the C++11 one,
actually using a generalized lambda capture (corresponding to the
handwritten C++11 closure type).

All three implementations use std::async (with a deferred launch policy,
a nice use case for it!) under the hood. It's certainly an overkill for
our use case, as we don't need the std::future, but at least std::async
does all the plumbing for us.

a611a9f537 QCOMPARE: allow mixed-type comparisons
There's no reason to restrict the LHS and the RHS to the same type
like it was done before. That just leads to lots of casting. or use
of QVERIFY(. == .) instead of QCOMPARE, with all the disadvantages
like no printing of the LHS and RHS values.

The rationale given in the documentation for this behavior is
incorrect. Ensuring that RHS and LHS have the same type by no means
ensures that no implicit conversions take place when calling
operator==. Proof:

   QCOMPARE(QLatin1Char('a'), QLatin1Char('a'));
   // instantiates
   qCompare<QLatin1Char, QLatin1Char>
   // but calls
   operator==(QChar, QChar)

If the intent is to disable implicit conversions of the argument
types, then some serious metaprogramming magic would be needed, along
the following lines:

1. find out which op== overload is actually chosen
2. find that overload's RHS parameter type, assert it's the same as
   (possibly cv-qualified) T1.
3. ditto for the LHS parameter type and T2

This is not attempted here.

Fix the inconvenience this restriction caused by simply allowing
two types.

This cannot break existing code, since we didn't actually change
anything in the qCompare() overload set. All we do is implement the
existing qCompare<T1, T2>() overload.

[ChangeLog][QtTest] QCOMPARE can now be used for mixed-type
comparisons.

759af3e5ad Centralize the check that the floating point implementation follows IEEE754
C++ does not specify which kind of floating point implementation is
being used. The C Standard doesn't either, but it includes a normative
reference for implementations adoping it (ISO/IEC 9899:2011 Annex F).

There are a few existing checks in qfloat16.cpp; move them to qglobal.cpp
(next to the other, similar checks), and improve them by actually
checking that the radix used for floating point numbers is 2.

07942adb77 xcb: Add experimental legacy support for native X11 painting
This commit revives the old native QPixmap and QPaintEngine
implementations that were present in Qt4. The backing store supports
regular raster windows in this commit. Support for render-to-texture
widgets and OpenGL compositing will be added in a follow-up commit.

ecf440d89d Fix CSS line-height property multiplier value handling
CSS style such as "line-height: 1.5;" should be used as a multiplier,
but Qt uses it as percentage which makes line spacing way too small. To
workaround this, convert it to percent and use as
QTextBlockFormat::ProportionalHeight instead.

7d4bf142d7 QUuid: add fromString(QStringView/QLatin1String)
As for the formatting code, de-duplicate the parsing code by only
parsing char*s, converting QChars to Latin-1 first in a small buffer.

The QUuid(const char*) ctor performed no length checking, relying
instead on the checks performed within _q_uuidFromHex(), which
includes an implicit check for premature end (because NUL is not
a valid token for the parser).

The (QString) and (QByteArray) ctors did perform length checking.
To the extent possible, this is removed, since it is handled by
_q_uuidFromHex(). Failure cases need not be optimized. Only the
QLatin1String overload needs to do some checking, because views in
general are not NUL-terminated. The QStringView overload can just
append a NUL when it converts to Latin-1.

The only check I added to _q_uuidFromHex() is that for src ==
nullptr. It would otherwise be duplicated in several callers.

While touching the internal functions, port to passing and returning
by value.

Saves 1.6KiB in text size on optimized GCC 6.1 Linux AMD64 builds,
even though we added new API.

Port some users to the new functions. Expand fromString() test.

[ChangeLog][QtCore][QUuid] Added fromString(QStringView/QLatin1String).

126c4eae84 Split Q_COMPILER_UNICODE_STRINGS: add Q_STDLIB_UNICODE_STRINGS
Since commit bf2160e72c, we can rely on
charNN_t support in all compilers except MSVC 2013, and since that
commit, we use (in 5.10, not 5.9, yet)

  !defined(Q_OS_WIN) || defined(Q_COMPILER_UNICODE_STRINGS)

when we only need charNN_t, the type, as opposed to its library
support (u16string, char_traits<char16_t>, ...).

This patch splits the Q_C_UNICODE_STRINGS macro into two, adding
Q_STDLIB_UNICODE_STRINGS for when we need std::uNNstring, leaving
Q_C_UNICODE_STRINGS for when we need just charNN_t support.

In QDebug, when constructing a QChar out of a char16_t, cast to ushort
first, since QChar(char16_t) was only officially introduced in Qt 5.10.

[ChangeLog][Potentially Source-Incompatible Changes] The internal
Q_COMPILER_UNICODE_STRINGS macro is now defined if the compiler
supports charNN_t, even if the standard library does not. To check for
availability of std::uNNstring, use the new Q_STDLIB_UNICODE_STRINGS
macro.
