QMainWindow tries to avoid memory allocations by caching tab bars that
are no longer used. That cache is populated when the layout is
activated.
The layout might never be activated when the main window is never shown,
in which case adding and removing dock widgets at runtime will
continuously allocate more memory for tab bars that are created.
A workaround is to call QMainWindow::layout()->activate() explicitly in
application code, once all dock widgets have been removed. This change
avoids that applications have to do that.

When hiding a popup by clicking outside of its area, a window is closed.
Depending on the platform specific implementation details, this can
result in multiple calls to QWidgetPrivate::setVisible(false). The first
one from the handling of the close event in QWidgetWindow::event; the
second from the destruction of the window in QWindow::event.
Since the first call already sets the Qt::WA_WState_Hidden flag before
calling QWidgetPrivate::hide_helper, we can test if the flag is set
and skip the second call if it is.
The included test does not reproduce the issue, as that issue only
reproduces if the close event is generated by the mouse event handling
in the Cocoa platform plugin (which doesn't call QWidget::close, but
rather sends a native close event to the platform window). However, it
verifies that the fix doesn't introduce any regressions.

The changing of the pointer of QApplicationPrivate does not transfer
focus properly. It updates the pointer, but it doesn't deliver events
or update the widget hierarchy's focus chain. The result is that
multiple line edits might show a blinking cursor.
Instead, use QWidget::setFocus when the focus proxy has changed while
it had focus, and pass OtherFocusReason rather than NoFocusReason.
Add a basic test for QWidget::focusProxy, which exercises this code
path and verifies that pointers are consistent when focus changes as
a side effect of modifying the focusProxy.

Qt assumes that ascent+descent is the bounding height of the
text, but for historical reasons, the ascent for some fonts
will not contain the diacritics. On Windows, the preference
is to use data from the OS/2 table which were explicitly
invented to work around this, but on other platforms we
are not respecting this table. This causes a text layout
that looks fine on Windows to have overlapping characters
on e.g. macOS.
To make vertical metrics (ascent, descent, leading) consistent
across all platforms, we don't blindly trust the values we get
from the underlying font system, but apply in the following order:
1. If OS/2 table exists and USE_TYPO_METRICS flag is set, we
use the typo metrics from OS/2 table
2. If OS/2 table exists and USE_TYPO_METRICS flag is not set,
we use winAscent/winDescent from OS/2 and the line gap from
HHEA table.
3. If no OS/2 table exists, we try to get ascent, descent and
line gap from the HHEA table.
4. If the HHEA table does not exist (not an SFNT), we fall back
to the system-provided metrics. (on macOS, we know the
system-provided metrics will match the data in HHEA, so we
skip parsing that table and use the data from CoreText if
there is no OS/2 table).
