ac0a266e75 testlib: Don't disable watchdog when the macOS crash reporter is enabled
The debuggerPresent() function was used both to decide whether we should
print our own stacktrace, and if we should start the watchdog timer, but
checking for the macOS crash reporter only applies to the former usecase.

The crash reporter check has now been split into a separate function, only
used to decide whether we should print our own stacktrace or not.

967e55a628 Allow creating a valid QColorSpace one value at a time
The change to using setters left a quirk from the previous un-mutable
design where you couldn't set values on an invalid color space and
create a valid one.

This changes that so it works as expected for an imperative API, but
is also needed for the declarative QML bindings.

d6ba2ae441 Consolidate some Q(Date|Time)+ methods to call calendared versions
The string-returning methods were in any case delegating to either a
local static or QLocale methods that delegate to their calendar
variants, so do the default-calendar step early and reduce the number
of distinct code-paths, along with the gross number of lines of code.

In the process, short-cut past QDate::toString() when we can save its
switch and go direct to the toString{Text|Iso}Date() it's calling.
Tidy up somewhat in the process.

a5be18cc7d rhi: Enable sampler address mode W in the API
Internally this is already supported by all backends. The frontend was just
not exposing addressW, instead defaulting to the (arbitrarily chosen) ClampToEdge.

Add the parameter to newSampler(), but make it optional, defaulting to the more
natural Repeat (because that's what one would get with OpenGL for WRAP_R by default)

601ce9e08a Implement moving of a single file system entry to the trash
This implements the operation for Windows, macOS, and Unix, for now
only as a private API (since QFileSystemEngine is private). This adds
the capability as a testable function; public API to be agreed on and
added in a separate commit.

The Unix implementation follows the freedesktop.org specification [1]
version 1.0.

[1] https://specifications.freedesktop.org/trash-spec/trashspec-1.0.html

On macOS and Windows, native APIs are used, with each having some
limitations:

* on macOS, the file in the trash won't have a "put back" option,
  as we don't use Finder automation, for the reasons provided in the
  comments
* on Windows, we might not be able to use the modern IFileOperation
  API, e.g. if Qt is built with mingw which doesn't seem to provide
  the interface definition; the fallback doesn't provide access to
  the file name in the trash

The test case creates files and directories, and moves them to the
trash. As part of the cleanup routine, it deletes all file system
entries created. If run on Windows without IFileOperations support,
this will add a file in the trash for each test run, filling up
hard drive space.

6e1d70ae12 QPushButton: only trigger button when click occurs within the bevel rect
On the mac, the push button's bevel doesn't cover the entire widget
rectangle, but is smaller to leave space for focus frame, shadow, and
in general to meet style guidelines. Without this change, a click
anywhere inside the widget would activate the button.

QAbstractButton::hitButton can be reimplemented to limit the area in
which the button is triggered. However, getting the rectangle also
requires an addition to QStyle, so that we can query
QStyle::subElementRect for the actual area the button's bevel covers.

As a side effect, tests that use QPushButton and assume that it
responds to clicks at position 0,0 have to be fixed so that they
don't fail on mac.

a611c632bb Add QWindow::startSystemMove and startSystemResize
This can be used to create custom client side window decorations.

Refactors the xcb implementation to use edges instead of corners and we now use
the last mouse position for `root_x` and `root_y` in the `_NET_WM_MOVERESIZE`
event. Touch has also been changed, so just pick a point that's currently being
pressed.

The workaround for QTBUG-69716 has now been moved to QSizeGrip, as the comment
in the bug report says that it should ideally be fixed at the widget level.

On Windows, we no longer abort when GetSystemMenu returns false. I assume this
code was added to check whether the window didn't have any decorations and not
resize in that case. However, since the point of this patch is to let windows
without native decorations resize/move, it makes most sense to remove the
check.

Adds a manual test, which calls QWindow::startSystemMove and startSystemResize
on touch and mouse events.

[ChangeLog][QtGui] Added API for starting interactive window resize and move
operations handled by the system.

f21a6d409e QStringList: use local storage in removeDuplicates()
If available, use a C++17 std::pmr::unordered_set with a monotonic
buffer resource and a 256-byte stack buffer to avoid the per-element
allocations of QSet.

Results on my machine:

When interpreting the data, take into account that each iteration
contains _also_ a deep copy of the QStringList d/t the detach from
'input'.

The pattern is used elsewhere in Qt, so I've put the class that
implements the seen set into a private header file and used in some
other places I found.

bf330a8f03 QGestureManager: fix one (of many) inefficient loop(s)
I showed QGestureManager to a colleage and I just couldn't avert my
eyes...

Also remove a pointless container::clear() call (the data member's
dtor will do that implicitly).
