QRect::center() should be defined for any
QRect(x1,y1,x2,x2), INT_MIN <= x1, x2, y1, y2 <= INT_MAX
because the average of two signed integers is always
representable as a signed integer.
But not when it's calculated as (x1+x2)/2, since that
expression overflows when x1 > INT_MAX - x2.
Instead of playing games with Hacker's Delight-style
expressions, or use Google's patented algorithm, which
requires two divisions, take advantage of the fact that
int is not intmax_t and perform the calculation in the
qint64 domain. The cast back to int is always well-
defined since, as mentioned, the result is always
representable in an int.
Fix a test-case that expected a nonsensical result due
to overflow.

This reverts commit 90de48493be283b9afb249f6a0fd8dbd8958517d.
The call isn't necessary, but invokes undefined behavior.
It invokes undefined behavior because deleteTLSysExtra() is called
from deleteExtra(), which is called from ~QWidgetPrivate(), which is
called from ~QObject(). Thus, by the time we call q->windowType()
within setWinId(), q is no longer a QWidget, but only a QObject, and
calling a QWidget member function then is UB.
UBSan confirms:
qwidget_p.h:300:5: runtime error: downcast of address 0x2afdd4053620 which does not point to an object of type 'QWidget' (the Q_Q macro)
0x2afdd4053620: note: object is of type 'QObject'

0x2afdd4053620: note: object is of type 'QObject'
It is also unnecessary:
deleteTLSysExtra() is called from two places: QWidget::destroy() and
deleteExtra(). deleteExtra() is only called from ~QWidgetPrivate()
which is only called from ~QObject() called by ~QWidget(), which,
however, already calls QWidget::destroy(). QWidget::destroy(), in
turn, unconditionally (for non-desktop widgets, at least) calls
setWinId(0) itself.
So fix the UB by removing the call without replacement.

The printf-style version of QDebug expands to a lot less code than the
std::ostream-style version. Of course, you pay in type safety (but
compilers warn about it these days), you cannot stream complex Qt
types and streaming QStrings is awkward, but in many cases you
actually improve on readability.
But the main reason is that something that's not supposed to be
executed under normal operation has no business bloating executable
code size.
This is not an attempt at converting all qWarnings() to printf-style,
only the low-hanging fruit.
In this first part, replace
qWarning() << ""
with
qWarning("...").
Had to fix broken qImDebug() definition. Instead of defining it as
a nullary macro in the QT_NO_DEBUG case and as a variadic macro in
the other, define it in both cases, as is customary, as a non-function
macro so that overload selection works without requiring variadic
macro support of the compiler.

QReadWriteLock is supposed to be a better alternative to QMutex when there
are only a few writers but potentially lots of reads. However, in practice
the previous implementation was much slower, unless you really do a lot of
work with the lock for read and you have lots of contention.
Indeed, the previous implementation was locking a QMutex both for lock, and
unlock (making it already at least twice as slow as QMutex).
This new implementation brings QReadWriteLock back to the same level as QMutex:
- No memory allocations in the uncontended case (almost no overhead allowing to
create many of them in classes)
- Lock-free if there is no contention
Should support up to 2^31 concurrent readers on 64 bit platforms, and 2^28

- Clear the first responder for the NSWindow under

- Use an autoreleasepool to clean up temp objects
