The qmake code to read output from dependency-generation was adding
QByteArray values to a QString, thereby tacitly converting from UTF-8;
this is misguided. Hopefully, the command emits its output in the same
local 8-bit encoding that QString knows to convert from.
Simplified needlessly verbose loops (that violated Qt coding style) in
the process.

TSAN does not understand the futex system call.
Now, in QMutex and QSemaphore usage, futex is always wrapped by
atomic operations that always do an acquire (before waiting) and
a release (before waking waiters). That alone realizes a
synchronizes-with, and since Qt uses std::atomics, TSAN knows
what's going on and does not complain.
But what if one uses futex directly, or we change the
algorithms, or introduce some other new synchronization
primitive somewhere? Luckily TSAN offers annotations for this
that we can use.
This patch annotates the main entry point for the futex syscall
with a pair of acquire/release semantics. A futex call
guarantees total ordering on the operations on the futex
word(s), whether the call succeeds or fails.

The old code iterated over the peer list, inserting active peers into
a QSet, curiously not stopping to search for clients if it had already
determined the peer to be active.
It then iterated over the peers again, storing the indexes of the
peers it had determined to be active in the first loop, in a QList.
It _then_ iterated over the index list, in reverse, calling removeAt()
on the peers list.
<sean parent>That's a remove_if!</sean parent>
The twist is, that only some maximum number of inactive peers should
be removed, just enough to bring the number of peers below a
predefined number.
To solve, use a lambda that keeps track of the number of times it has
returned true, returning false once the count drops to zero. We can't
use a mutable lambda here, since the STL algorithms are allowed to
copy the predicate as many times as they wish, and, indeed, remove_if
is commonly implemented by calling find_if. But the standard
guarantees exactly one application of the predicate per element, so we
can assume that we're not called again on the same element, and
therefore keep a reference to an external count.
With this, what was a horrible mess becomes a single call to remove_if.
Also change a while(--n) c.removeFirst() loop to a single call of
range-erase.

9204b8c31e broke font matching on Windows.
This was then attempted fixed by bcd2fa484a,
but this caused an infinite recursion for some cases, so it was reverted
again by 9d1905da9c.
The original issue was that if we populate a specific face of a family,
such as "Arial Black", then the typographic/preferred name will be
detected as "Arial" and this family will be set as populated=true, even
though we have not yet registered any additional subfamilies. In this case,
we need to call populateFamily() for the typographic family name to
ensure we get Windows to enumerate all the subfamilies in that family
before it sets it as populated=true.
But this broke for some fonts where the font naming was unconventional.
In particular, "Yu Gothic" would have its Japanese name as the
typographic name, and there would be no font in the system where
the old-style font family name matched the typographic name. In
that case we would go into a loop where we would try populating
"<Japanese font name>", Windows would translate this to "Yu Gothic", we would
translate it back to "<Japanese font name>", ad infinitum.
In order to avoid the infinite recursion, we add a recursion guard
as well, ensuring that we never call populateFamily() for the main
family we are currently populating.

to request different faces of a font family after a specific type face

Unlike any other implicitly shared container, QString/QByteArray
have a "lazy detach" mechanism: their operator[] returns a
special object; assignment into that object will actually
detach.
In other words:
QString a("Hello");
QCharRef c = a[0]; // does not detach
c = 'J'; // detach happens here
This allows this behavior:
QString a("Hello");
QCharRef c = a[0];
QString b = a;
c = 'J'; // detach happens here
assert(a == "Jello");
assert(b == "Hello");
Note that this happens only with operator[] -- the mutating
iterator APIs instead detach immediately, making the above code
have visible side effects in b (at the end, b == "Jello").
The reasons for this special behavior seems to have been lost in
the dawn of time: this is something present all the way back
since Qt 2, maybe even Qt 1. Holding on to a "reference" while
taking copies of a container is documented [1] to be a bad idea,
so we shouldn't double check that the users don't do it.
This patch:
1) adds an immediate detach in operator[], just like all other
containers;
2) adds a warning in debug builds in case QByteRef/QCharRef is going
to cause a detach;
3) marks operator[] as [[nodiscard]] to warn users not using
Clazy about the (unintended) detach now happening in their code.
This paves the way for removal of QCharRef/QByteRef, likely in
Qt 7.

setHtml() or setMarkdown() can result in attempting to load resources
such as images that are needed to render the page. Whenever the
resource has a relative URL, loading depends on the baseURL having
already been set so that a complete URL can be constructed.
QTextDocument::resource() is called to load images, and uses baseUrl().
A little later, QTextBrowserPrivate::resolveUrl() is given an URL that
already has been extended with the baseURL if known; but it has its own
logic to resolve the resource URL against currentURL, or else to treat
it as a local file path if a file exists at that location. The autotest
was relying on this fallback to the local relative file path before; but
now it tests both with a local filename in the current directory for the
source HTML and also with a fully resolved source URL containing the
complete file path.
Also made minor style improvements in tst_QTextBrowser's TestBrowser class.
