de3785b8bc QVersionNumber: add fromString(QStringView/QLatin1String) overloads
The parsing code anyway operated on a QByteArray created from
toLatin1(), so expose this to the user by providing a QLatin1String
overload.

Also provide a QStringView overload, since we can. Port one user (in
qmake) to the new overload.

[ChangeLog][QtCore][QVersionNumber] Added QStringView and
QLatin1String overloads of fromString().

399ab058c9 Add front()/back() to QString, QStringRef, QByteArray and QLatin1String
These STL-compatibility functions are present on our generic
containers, but not on the string classes.

[ChangeLog][QtCore][QString/QStringRef/QByteArray/QLatin1String] Added
front() and back() for STL compatibility.

5dc1e08c8c Add qConvertTo{Utf8,Latin1,Local8Bit,Ucs4}() and corresponding QStringView methods
Like the qt_compare_strings()/qCompareStrings() split, distinguish
between the internal and exported functions.

Because of the circular dependency between qstring.h and qvector.h,
the inline toUcs4() function has to be in qvector.h.

At some point, we need to refactor the headers so qvector.h is lower
in the dependency chain than qstring.h. It's not the first time this
bites.

95263dbf7a Add a test for container API symmetry
Akin to the successful tst_QStringApiSymmetry, add such a test for
generic containers, too. Yes, we have tst_collections, but it's a
cut'n'paste mess that makes it hard to systematically perform
cross-class checks for consistency. This new test, still in its
infancy, uses templates and thus ensures that exactly the same checks
are run on all containers.

Starting out with front()/back(), which the string classes were found
to lack, we will build this test up, as we did and continue to do with
the string API one.

bbb67ca32c Fix tst_Collections for gcc/arm
- Alignment test was not compiling or passing on GCC / arm
- Using C++11 alignas() enforces maximum limit for the alignment, which
  at least on GCC / arm is __BIGGEST_ALIGNMENT__ multiplied by 8
- On GCC 6.2.0 / x86_84, maximum alignment accepted by alignas is 128
- On GCC 5.3.0 / arm, maximum alignment accepted by alignas is 64
- This change calculates biggest tested alignment on ARM targets
  and compilers supporting alignas() to the value calculated
  from __BIGGEST_ALIGNMENT__

d2388f15e7 Add QMetaObject::invokeMethod() overloads for function pointers
The new overloads do not accept parameters for the invoked function, this
use case is handled by using lambda.
Overloads for non member function pointers and functors are separated as
the return type is not retrieved in the same way.
Move QSlotObjectBase, QSlotObject and QFunctorSlotObject from
qobject_impl.h to qobjectdefs_impl.h in order to make them available in
qobjectdefs.h.
Update autotests of previous overloads because of a soft break in source
compatibility: passing null literals (0, NULL, nullptr, etc.) for the
second parameter of invokeMethod() is not supported anymore.

9a0d47bcf1 tst_largefile: fix the mapOffsetOverflow case to match actual behavior
Unix mmap(2) system calls do allow for mapping beyond the end of the
file, though what happens after you try to dereference the pointers it
gives is unspecified. POSIX[1] says that implementations shouldn't allow
it:
 The system shall always zero-fill any partial page at the end of an
 object. Further, the system shall never write out any modified portions
 of the last page of an object which are beyond its end. References
 within the address range starting at pa and continuing for len bytes to
 whole pages following the end of an object shall result in delivery of
 a SIGBUS signal.

However, Linux allows this in read-write mode and extends the file
(depending on the filesystem).

Windows MapViewOfFile never allows mapping beyond the end.

46351b4e60 QColor: port to QStringView
... leveraging the existing support for QLatin1String, which is the
char equivalent of QStringView.

The only noteworthy changes here are the port of the low-level
functions to size_t and that the internal template function,
setColorFromString(), can now take its argument by value, since only
views are ever passed to it anymore.

In the test, used new QTest::addRow() to format test names, and
introduced temporaries to avoid re-calculating the same input values
for every check.

Only test for xcb specific sub-features if xcb is available in
the first place - not the case with Boot2Qt builds.

7180236063 QStringView: improve manual overload management
We want to prevent

  QStringView(QChar|QLatin1String|QByteArray|const char*)

from compiling as QStringView(QString(...)), so I added = delete'ed
ctors for these types to QStringView. However, that makes QStringView
participate in overload resolution for these types. Even if the
QStringView ctor will always fail to compile, the presence of these
ctors alone makes calls to functions overloaded on QString and
QStringView ambiguous:

   f(QStringView);
   f(QString);
   f(foo);        // ambiguous
   f(QChar('f'))    // ambiguous
   f(QLatin1String(foo)); // ambiguous
   f(QByteArray(foo));    // ambiguous

Fix by making the QString and QStringRef constructors templates
constrained to accept only these two types. This should also help to
move the QStringView definition to before the QString one (as soon as
we get rid of or start to ignore QString::Null), simplifying a lot of
code in qstring.h down the line.

This should also fix MSVC's accepting of two user-defined conversions
which caused static non-compile-tests to fail in the initial
QStringView patch, and which were therefore removed. This patch brings
them back.
