d934fd7f54 Send MouseMove events without buttons if the press closed the popup
With nested popup widgets, pressing a mouse button on the lower
popup will close the active popup. MouseMove events that are generated
before the button is released again should not have that button
included, as it is likely to result in incorrect state handling in
the widget. This change removes all buttons from the MouseMove event,
which is the second best option.

This is mostly consistent with the behavior when closing a popup and
no other popup remains. The widget underneath will get MouseMove
events without the respective button included.

This change doesn't include a fix for the final release event, which
should ideally also not be delivered to the remaining popup, as it
never got a corresponding press event. Qt has already reset the states
in which it stores which widget received the press event at the time
the release is generated, such as qt_button_down and qt_popup_down.
So we can't separate a release grabbed by a newly opened popup (which
we want) from a release to the popup that became active after closing
(which we don't want).
However, widgets can more easily work around this issue, and the risk
of breaking things by changing the code further becomes too high.

2e0c29a4bb itemviews: Use the start of the current selection when getting the range
When doing a shift-select while moving the mouse then the start point
should be based on the start of the current selection and not the
pressed position. If there is no current selection start index, then
we can safely depend on pressed position as this will be the previous
index pressed on.

0613bf5d16 QTextEdit: remove the cursor when a read-only textedit looses focus
A read-only text edit with Qt::TextSelectableByKeyboard shows a steady
cursor to indicate to users that they can select the text, but not edit
it. When the control receives focus, it doesn't turn on blinking, but
explicitly sets cursorOn to true.

When focus is lost, then cursorOn needs to be reset to false to make
the cursor disappear, even if the blinking (as indicated by the poorly
named cursorVisible variable) is not on.

d4a4202caa widgets: Sync client rect of paint-on-screen widgets during resize

this applies to paint-on-screen widgets as well. The same goes for
how the widget repaint manager tracks dirty rects. Internally we
were also calling paintOnScreen() with client rects, so the use
of geometry() in the resize handler was likely a bug/oversight.

0b5a1100ff Doc: Adjust offline style for the litehtml rendering engine
Qt Creator now has the option to use the litehtml backend as a
replacement for the QTextBrowser-based help viewer.

Fix a few issues that the offline style has with the litehtml renderer:

- Fall back to using an unordered list for the navigation bar.
- Remove the background image for #buildversion and adjust font size.
- Adjust the generated padding around code snippets.

Keep the script that switches the offline-simple.css style to the
full offline style (offline.css) for JavaScript-enabled browsers.
The litehtml backend in Qt Creator will handle this switch internally.

With these changes, the generated offline documentation looks
acceptable when rendered with QTextBrowser, litehtml, or desktop
web browsers.

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).

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).

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().

ba5e2ce49a forkfd: fix forkfd_wait when FFD_USE_FORK was active
If we detected that the OS supports a version of system forkfd (Linux
pidfd, FreeBSD procdesc), the forkfd_wait() function was using only the
system waiting implementation, which of course can't work for file
descriptors created with FFD_USE_FORK. So just detect EBADF and attempt
again.

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

4605583fec forkfd: introduce forkfd_wait4() that takes options
"wait4" because it looks like the wait4() BSD function, which has the
signature:

       pid_t wait4(pid_t pid, int *wstatus, int options,
                   struct rusage *rusage);

And because ours also has 4 parameters.

Having options is important anyway. I might want to add some more later,
but we can't really support them with the fall back implementation (in
fact, we don't honor WNOHANG in the fall back implementation either).

b1e3f33a28 Call post routines from ~QGuiApplication
Currently depending if user uses QApplication
or QGuiApplication we end up in different behavior
when running post routines. For example QApplication
destructor calls post routines before stopping event dispatcher,
In case of QGuiApplication post routines are called
from QCoreApplication destructor, so no more event dispatcher.
This behavior is not consistent and creates troubles
when releasing resources of web engine.

Attached test will hang on windows with QGuiApplication,
however works fine with QApplication.
