For some use cases, vertical subpixel positioning may be
useful, as it allows you to vertically align text with
other painting primitives. This does impose an overhead,
so we make it opt-int with a render hint on the painter.
Note that this is only supported on Freetype currently.
It might be possible to support on older macOS versions,
prior to Mojave (which has disabled subpixel positioning
entirely), but since it would have limited usefulness
and Freetype is cross-platform anyway, I skipped that.
Note: This drive-by-fixes an issue with subpixel
positioning where glyphs would always be offset by 1/64,
because we added the aliasing offset *after* we had
determined the closest subpixel position. The idea of
this, as far as I can understand, is rather to snap to
nearest subpixel position upwards, not to add an offset
to all glyphs, so it should be added before finding the
correct position. It had a subtle visual effect when
animating the position. It might be that we could get
rid of it entirely, as I haven't been able to reproduce
any issues with that, but I have moved it instead, to
match what I believe the intention was.
[ChangeLog][QtGui][Text] Added render hint flag
QPainter::VerticalSubpixelPositioning which will position
text at subpixel positions vertically whenever supported.
In absence of this, text position will be rounded
vertically as before.

At the moment we have two main strategies for dealing with move
assignment in Qt:
1) move-and-swap, used by "containers" (in the broad sense): containers,
but also smart pointers and similar classes that can hold user-defined
types;
2) pure swap, used by containers that hold only memory (e.g. QString,
QByteArray, ...) as well as most implicitly shared datatypes.
Given the fact that a move assignment operator's code is just
boilerplate (whether it's move-and-swap or pure swap), provide two
_strictly internal_ macros to help write them, and apply the macros
across corelib and gui, porting away from the hand-rolled
implementations.
The rule of thumb when porting to the new macros is:
* Try to stick to the existing code behavior, unless broken
* if changing, then follow this checklist:
* if the class does not have a move constructor => pure swap
(but consider ADDING a move constructor, if possible!)
* if the class does have a move constructor, try to follow the
criteria above, namely:
* if the class holds only memory, pure swap;
* if the class may hold anything else but memory (file handles,
etc.), then move and swap.
Noteworthy details:
* some operators planned to be removed in Qt 6 were not ported;
* as drive-by, some move constructors were simplified to be using
qExchange(); others were outright broken and got fixed;
* some contained some more interesting code and were not touched.

The change creates a slight source incompatibility. The main
things to take care of are
* code using printf statements on list.size(). Using qsizetype in
printf statements will always require a cast to work on both 32

* A few places where overloads now get ambiguous. One example is
QRandomGenerator::bounded() that has overloads for int, uint and
double, but not int64.
* Streaming list.size() to a QDataStream will change the format
depending on the architecture.

This is a commit in preparation for an upcoming change in QtQuick.
We want to store the resolved functions for managing VAOs somewhere;
the "least worst" choice is next to the all other function resolvers,
which are in QOpenGLContext(Private).
To avoid moving the VAO resolvers themselves, leave a hook in
QOGLCPrivate, similar to e.g. the texture function resolvers. The hook
gets populated when the VAO resolvers for a given context are
requested.
This removes memory management burden from the users of those functions
(again, just like other function resolvers), and makes the
initialization of the functions automatic.

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).
