5f87fb8813 QLineEdit: Include the horizontal margin in minimumSizeHint
The margin is respected in the sizeHint, but not in the minimumSizeHint.
Since the latter should be the former for a single character (as per the
documentation promising enough space for one character), the margin
calculation needs to be identical.

Adjusting the documentation nevertheless, as there are characters that
won't fit either way. As reported, the permyriad character doesn't fit
even with this fix on macOS, as the core graphics API we are using
doesn't report a glyph-index for U+2031 (so our existing assumption
that 'W' is the widest character is still the best we can do).

b3b51a7665 Fix deprecation warnings for QInputDialog::getDouble()
The way this was done didn't really make sense. The change added
an overload with one additional argument. The deprecation warning
would have now forced everybody to explicitly specify all arguments
to avoid the warning.

Instead, keep both overloads in 5.15, but document them as one method.
Remove the old version in Qt6 and move the default arguments to the
new version.

The current approach used is based of the discussion present in

be considered a temporary solution until the issue is properly addressed

02d595946f QCborValue::fromCbor: Apply a recursion limit to decoding
A simple 16k file can produce deep enough recursion in Qt to cause stack
overflow. So prevent that.

I tested 4096 recursions just fine on my Linux system (8 MB stack), but
decided 1024 was sufficient, as this code will also be run on embedded
systems that could have smaller stacks.

[ChangeLog][QtCore][QCborValue] fromCbor() now limits decoding to at
most 1024 nested maps, arrays, and tags to prevent stack overflows. This
should be sufficient for most uses of CBOR. An API to limit further or
to relax the limit will be provided in 5.15. Meanwhile, if decoding more
is required, QCborStreamReader can be used (note that each level of map
and array allocates memory).

... when we are not using the FFD_USE_FORK flag. We use the FFD_USE_FORK

does and see the comment in this commit on why it's safe to use it.

defd49f7bf forkfd: add FFD_VFORK_SEMANTICS flag
This flag asks forkfd() to use vfork semantics wherever available. That
is, suspend the calling process execution until the child either does an
execve(2) or _exit(2). The advantage of that is that it puts lower
pressure on the OS VMM system, as the number of pages that need to be
copy-on-write duplicated is much smaller (still not zero, as at least
the stack in the child will be written to).

However, the only implementation that supports using this flag for now
is Linux's pidfd. It would be possible to add to FreeBSD, but pdfork(2)
does not have a flag for this behavior -- if it gets one, we can add
support for it later. Everywhere else, we need to force the child to not
exit until we store the child process's PID in the ProcessInfo structure
we allocated, which means the parent process must run before we even
return from forkfd().

pidfd, FreeBSD procdesc), the forkfd_wait() function was using only the
system waiting implementation, which of course can't work for file

again.

If the file descriptor is neither one of our pipes nor a system forkfd,
bad things will happen...

02fa39ed22 macOS: Flush sublayers via separate IOSurface backingstores
Flushing sublayers via QImage copies of the root IOSurface was causing
performance regressions due to the constant allocations of new images
each frame.

We now re-use the QCALayerBackingStore implementation for sublayers,
which gives a dynamic swap-chain.

We're still paying the CPU cost of the copy from the root backingstore
to the layered backingstores, as well as the memory cost, but at least
improves the situation.

We do not try to be smart and paint directly into the sublayers,
as that would leave the root backingstore stale, potentially causing
glitches when views are repositioned. Investigating this is left
for future work.

0446bf5ba3 CMake: Fix auto-detection of precompiled header support
PCH files were only used while building qtbase. Make sure the value
is exported to the BuildInternalsConfig file, so the value is re-used
when building other repositories.

Also disable PCH when building simulator_and_device iOS builds, because
CMake doesn't currently generate separate PCH files per architecture.

874c6b00dd Remove QSignalMapper::mappedWidget()
mappedObject() can do exactly the same thing, there's no need for a
mappedWidget() signal as well

This removes a reverse dependency between Qt Widgets and Qt Core where
QWidget pointers are being used inside Qt Core.

[ChangeLog][QtCore] Removed QSignalMapper::mappedWidget. Connect to
mappedObject instead, and use qobject_cast<QWidget *> to handle Widgets.
