84f2792597 qmake: Support .dll.a import libraries for MinGW builds of Qt
CMake's default import library extension for MinGW is .dll.a. The code
in qt.prf that resolves the values of the QT variable expected an .a
extension.

To play well with CMake world we keep the the .dll.a extension for
Qt's libraries and teach qt.prf to handle both. In order to do that we
need to check for the existence of the .a or .dll.a file. If none of
these candidates was found we print a warning and fall back to the old
behavior.

b73809f30c CMake: Fix incorrect paths in build instructions message
When doing a top-level build,
QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX is not set in the
top-level scope. There's no point really in using the relocatable
path anyway, given this will only be displayed once when either
configuring qtbase or qt6.

Just use CMAKE_INSTALL_PREFIX directly.

It used to be called HAVE_DASH_UNDEFINED_ERROR, but that always
cause Coin to print the compile check as the first build error snippet
because it contains the word "error", and whenever you get emails from
Gerrit the first snippet is always this compile check.

Rename it to avoid confusion in emails and Coin status reports.

f9940b15f7 Fix breakage of QPushButton on macOS when a style sheet was set
Amends comment 6e1d70ae12, which
introduced SE_PushButtonBevel so that QPushButton could ignore clicks
outside of the button's bevel.

In the macOS style, make sure that the framerect we pass to
NSButton::alignmentRectForFrame is the rect we receive from QPushButton
in the style options. The frame property of the shared NSButton* object
might not be initialized.

In the style sheet style, handle SE_PushButtonBevel the same ways as
Contents and FocusRect, as it is not a separately styleable property.

a7162704c8 CMake: Fix installation location of plugins in static builds of Qt
For static builds of Qt we installed the plugins into the lib
directory. However, they are expected in the plugins directory tree.

This happens, because we pass a value of an uninitialized variable to
ARCHIVE DESTINATION in the qt_install call in qt_internal_add_plugin,
and CMake defaults to "lib".

This flaw was introduced in b42feb02ce with the following intent:
"This patch also changes add_qt_plugin() to use the value provided in
INSTALL_DIRECTORY for ARCHIVE_INSTALL_DIRECTORY if no value is provided
for the latter."

The patch changed the value of arg_ARCHIVE_INSTALL_DIRECTORY but
missed to set the variable archive_install_directory, which is
actually used in the qt_install call.

We now directly set archive_install_directory and remove the unused
archive_install_directory_default variable.

that change, they were the roles that QAbstractItemModel had initialized

need "display" to map to Qt::DisplayRole by default; several tests in

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).

dde11715d3 CMake: Temporary workaround for static top-level Qt builds
Because find_package usually creates targets in a local scope,
qt_generate_prl_file fails to generate a .prl file that has
references to generator expressions like
"$<TARGET_FILE:Freetype::Freetype>" which references targets
that are not found in that specific scope (e.g Freetype target is
present in qtbase scope, but not qtsvg scope).

This happens in static top-level Qt builds, and thus fails the
configuration. While we try to figure out how to fix this adequatly,
don't generate .prl files in such a configuration.

2a767ab4bb CMake: Fix libraries in qt_lib_XXX_private.pri files for NMC
qmake_use.prf understands the _DEBUG and _RELEASE suffixes for
QMAKE_LIBS_XXX entries. The CMake configuration "Debug" is considered
for the _DEBUG entries, "Release" and "RelWithDebInfo" for _RELEASE.

The qt_lib_XXX_private.pri files are now generated in multiple steps:
1. The QT_LIBS_XXX information is generated per $<CONFIG> and written to
   .cmake files.
2. A preliminary qt_lib_XXX_private.pri file is generated, containing
   only configuration-independent data.
3. A custom command runs the QtGenerateLibPri.cmake script that combines
   the files from step 1 and 2 into the final qt_lib_XXX_private.pri
   file.

The same is done for mkspecs/qmodule.pri.

To be able to trigger custom commands from header modules, which are
interface libraries, we introduce one XXX_timestamp ALL target per
header module that creates a timestamp file. To that XXX_timestamp
target we add the pri file generation target as dependency.

Fixes: QTBUG-84348

d2833a3ce5 Ensure left/right/mid behave in a compatible way
QString and QStringRef did bounds checking for left/right/mid, whereas
QStringView was asserting on out of bounds.

Relax the behavior for QStringView and do bounds checking on pos/n
as well. This removes a source of potentially hidden errors when porting
from QStringRef (or QString) to QStringView.

Unfortunately, one difference remains, where QByteArray::left/right()
behaves differently (and somewhat more sane) than QString and
QStringRef. We're keeping the difference here, as it has been around
for many years.

Mark left/right/mid as obsolete and to be replaced with the new
first/last/slice methods.

385f0732d9 Add QPromise implementation
QPromise and QFuture created from it share the same internal state
(namely, QFutureInterface object). QPromise provides high-level
management of the shared resource, ensuring thread-safe behavior
on construction and destruction (also taking into account
QFuture::waitForFinished() semantics).

QFuture acts as a primary controller of QPromise via action
initiating methods such as suspend() or cancel(). QPromise is
equipped with methods to check the status, but the actual
handling of QFuture action "requests" is user-defined.

[ChangeLog][QtCore][QPromise] Added QPromise class to accompany
QFuture. It allows one to communicate computation results and
progress to the QFuture via a shared state.

20ba86262f Add since markers for the Qt::endl, etc.
The Qt namespace was introduced in 461e89ee1a which is only since 5.14

Also remove QTextStreamFunctions:: from the documentation of the
deprecated functions since the QTextStreamFunctions namespace is a syntaxic workaround.

Pick-to: 5.15
