We store both in a single memory structure, instead of two local
statics. By construction, we also ensure that the global PRNG mutex is
in a different cacheline from the global PRNG state itself.
Finally, we don't store the full system QRandomGenerator, since we only
need the type member from it.

This brings us to almost parity with the C++11 Random Engine API
requirements (see chapter 26.5.1.4 [rand.req.eng]). We don't implement
the templated Sseq requirements because it would require moving the
implementation details to the public API. And we don't implement the
<iostreams> code because we don't want to.

Since we don't document how many bytes one needs (it's 2496), it's
difficult for the caller to provide just enough data in the seed
sequence. Moreover, since std::mt19937 doesn't make it easy to provide
the ideal size either, we can't actually write code that operates
optimally given a quint32 range either -- we only provide it via
std::seed_seq, which is inefficient.
However, we can do it internally by passing QRandomGenerator to the
std::mersenne_twister_engine constructor, as it's designed to work.

Since we're adding a deterministic generator that inherently does not
use syscalls, and people should really use that one by default, there is
no point in optimizing the secure generator wrt syscalls. Besides,
keeping the random data in memory for longer than needed is likely
inadviseable.

The vast majority is actually switched to QRandomGenerator::bounded(),
which gives a mostly uniform distribution over the [0, bound)
range. There are very few floating point cases left, as many of those
that did use floating point did not need to, after all. (I did leave
some that were too ugly for me to understand)

There are three ways to set the application (Dock/task switcher) icon:
1. By setting an ICON in the project file
2. By calling QGuiApplication::setWindowIcon
3. By calling QWindow::setIcon
The third one was not working on macOS, despite being documented as
such: "The window icon might be used by the windowing system for example
to decorate the window, and/or in the task switcher."
We now update the application icon based on the active window,
unless a global application icon has been set using ICON, or
via QGuiApplication::setWindowIcon. The reason for not allowing
the window's icon to override a global application icon is that
the developer may have intended to set the document icon for a
window (to represent QWindow::filePath), and we don't want that
to affect the Dock icon of the application.
The role of QGuiApplication::setWindowIcon is a bit dubious in this,
as it's documented as "This property holds the default window icon",
which would indicate it should follow the same logic as above by not
letting it override the global ICON set in the project file, but this
would not allow runtime switching of the application icon, so the
QGuiApplication property is left as is. The property should probably
have been named QGuiApplication::applicationIcon initially.

The RENAME_NOREPLACE flag is supported for all Linux local filesystems,
since that can be easily checked by the VFS layer (it knows which files
exist and which ones don't). For non-local filesystems, the backend
needs support and that might need server-side support too. So we may get
EINVAL errors for those, in which case we fall back to link/unlink,
which in turn can fall back to rename().
EINVAL can also happen if we attempt to make a directory a
subdirectory of itself. In that case, we will attempt to link() it,
which will result in EPERM as we can't hardlink directories. Then we try
rename() again, which should result in the expected EINVAL.
