725fc4da44 Properly indent qtestlib's XML output
Also regenerate the expected output for tst_selftests, to match new
output. Changed one line source code in tst_seftests for the
same purpose.

eea930b4d7 QTest: fix -Wformat-overflow GCC warning
Says GCC:
    In function ‘char* QTest::toString(QPair<T1, T2>&) [with T1 = QWidget*; T2 = QEvent::Type]’,
       warning: ‘%s’ directive argument is null [-Wformat-overflow=]

Fix by re-using formatString(), once introduced for std::tuple.

As a side-effect, this gets rid of the funny double-quotes around the
output.

8e98a161e9 Long live std::pair!
Make QPair an alias for std::pair, and qMakePair just a forwarder
towards std::make_pair.

Why? Fundamentally to ditch a bunch of NIH code; gain for free
structured bindings, std::tuple and std::reference_wrapper
compatibility, and so on.

Breakages:

* Some that code manually forward declares QPair.
We don't care about it (<QContainerFwd> is the proper way).

* Some code that overloads on std::pair and QPair. Luckily
it's mostly centralized: debug, metatypes, testing macros.
Just remove the QPair overload.

* Usages of qMakePair forcing the template type parameters.
There are a handful of these in qtbase, but only one was actually
broken.

* std::pair is NOT (and will never likely be) trivially copiable.
This is agreed to be a mistake done by practically all implementations
in C++11, can can't be fixed without breaking ABI.
Some code using QPair assuming it's trivially copiable may break;
exactly one occurrence was in qtbase.

* QMetaType logic extracts the type names in two different ways,
one by looking at the source code string (e.g. extracted by moc)
and one via some ad-hoc reflection in C++. We need to make
"QPair" (as spelled in the source code) be the same as "std::pair"
(gathered via reflection, which will see through the alias)
when compared. The way it's already done e.g. for QList is
by actually replacing the moc-extracted name with the name
of the actual type used in C++; do the same here.
On libc++, std::pair is actually in an inline namespace --
i.e. std::__1::pair; the reflection will extract and store
"std::__1::pair" so we need an ad-hoc fix to QMetaType.

[ChangeLog][QtCore][QPair] QPair is now an alias to std::pair,
and does not exist as a class in Qt any more. This may break
code such as functions overloaded for both QPair and std::pair.
Usually, the overload taking a QPair can be safely discarded,
leaving only the one taking a std::pair. QPair API has not changed,
and qMakePair is still available for compatibility (although
new code is encouraged to use std::pair and std::make_pair
directly instead).

98ef376fb6 generate_expected_output.py: update generated expected_* files
In selftests.qrc, imposed alphabetic order (on stem of name, then on
suffix, effectively treating . as sorting before any letter) while
removing old tests and adding new tests and data.  Updated all non-csv
files and added many missing files.  (Not clear on csv support status;
the script seems to have dropped it after 5.6, but the test still uses
it.)

Left expected_crashes* alone (no new files added, no update to old) as
I don't get results resembling those anticipated.

Omitted printdatatagswithglobaltags, printdatatags due to dangling
hspace on output lines, which upset sanity-bot.  A change to the test
cpp is needed to make it viable to skip that dangling hspace.

c608ffc56a Improve pair-like class handling in tests
Currently when doing comparison with pair-like classes the fallback
toString method is called which returns a Q_NULLPTR thus not allowing
proper diagnostic of the values that triggered an error. This patch
adds support for QPair and std::pair to improve the tests output
readability.

[ChangeLog][QtTest][QCOMPARE] Now outputs contents of QPair and
std::pair on failure.
