Unlike the previous implementation, this implementation is locked:
only one initialisation is ever run at the same time. It is
exception-safe, meaning that a throwing constructor will restart the
process.
Also, start using the thread-safe behaviour that GCC has offered for a
long time and C++11 requires.

This test runs fine almost all of the time on systems with 1
processor, which were the norm when the test was written and are still
the way that the Qt Continuous Integration system works as of
today. But it falls flatly on multi-processor systems.
The root of the problem is that QSystemSemaphore recreates the
semaphore if it disappears underneath it. However, the recreation
process is not thread-safe at all: if two threads race to recreate it,
weird things might happen. strace on Linux shows that a thread got
stuck trying to acquire the semaphore:

This problem does not happen if the creation and destruction of the
QSharedMemory (which uses QSystemSemaphore) does not race with other
threads or processes attaching and detaching. For the threads test
it's easy. For the processes, we use stdin and stdout as a
communication channel.

There are more opportunities in QtCore and the rest of Qt to make signals
private instead of public. This is a test-dart to see if there is any
reason not to do this.
It would be nice to make QObject::destroyed private, but as it has a
default argument it would be source incompatible to anyone connecting
to the SIGNAL(destroyed()) instead of SIGNAL(destroyed(QObject*)).
Currently the function-pointer-based connect syntax does not accept
a functor (or lambda) with a different number of arguments than the
signal. Olivier says a fix for that might come in 5.1, but for now
the qfiledialog2 test is changed to not use that anymore.
Also, the function pointer for a private signal can not be assigned to
a local variable, so the qmetamethod test is changed to not do so
anymore.

In particular the macro used before this patch was attempting to get the

Similarly, the variadic macro driven test is no good, because it was

Internally, QObject and QMetaObject already leave out non-signal
methods when working with signals. This is possible because the
signals always come before other types of meta-method in the
meta-object data. Ignoring irrelevant methods is faster and can
save memory.
QMetaObject provides internal indexed-based connect() and
disconnect() functions. However, these functions currently take an
absolute method index as the signal specifier, instead of an
absolute _signal_ index. Hence, QMetaObject and friends must convert
from the method index range to the signal index range.
By providing an API that only considers signal indices, clients of
the index-based QMetaObject::connect()/disconnect() can provide the
proper signal index directly. Similarly, for the qtdeclarative
integration (QDeclarativeData hooks) the signal index can be passed
directly. This will eliminate most of the conversions back and forth
between signal index and method index, and some other redundant work
done by qtdeclarative's custom connection implementation.
There are some places where the behavior can't be changed; for
example, QObject::senderSignalIndex() will still need to return an
index in the method range, since that function is public API.
Changing QMetaObject::connect()/disconnect() to take an index in
the signal range will be done in a separate commit; this commit is
only an enabler for porting existing usage of those functions to
the new behavior.

Reimplementations of connectNotify() and disconnectNotify() can
assume that the signal argument is in normalized form, but after the
introduction of the Qt5 meta-object format, it could happen that it's
not.
The problem is that the internal QArgumentType class, which attempts
to resolve a typename to a type id, was calling QMetaType::type().
QMetaType::type() falls back to trying the normalized form of the
typename if the original argument can't be resolved as a type (this
behavior isn't documented, but that's how it works). This means that
e.g. QMetaType::type("const QString &") returns QMetaType::QString.
Since QMetaObjectPrivate::indexOfMethodRelative() (more specifically,
the methodMatch() helper function) prefers to compare type ids
over typenames (since the type ids are stored directly in the meta-
object data for built-in types), the method lookup would *succeed*
for signatures with non-normalized built-in typenames as parameters.
QObject::connect() would then think that it did not have to
normalize the signature (see "// check for normalized signatures").
The consequence was that the original, non-normalized form got
passed to connectNotify().
This commit introduces an internal typename-to-type function that
is the same as QMetaType::type(), except it doesn't try to normalize
the name. This way, the only place where normalization can occur in
the signature-to-meta-method processing is through the calls to
QMetaObject::normalizedSignature() in QObject::connect() itself.
The implication is that there are now cases where the method
signature will be decoded and processed twice, where processing it
once was sufficient before. On the other hand, it is consistent with
the pre-Qt5-meta-object behavior, where we predict that the
signature is already normalized, and only perform (comparatively
costly) normalization if the initial lookup fails.

This API will fully replace the const char *-based connectNotify()
and disconnectNotify() in Qt5; the old functions will be REMOVED
before Qt 5.0 final.
The new implementation fixes the long-standing issue of
connectNotify() not being called when using the (internal)
index-based QMetaObject::connect() (e.g., from QML).
As with the old API, there are still two "unintuitive" behaviors
concerning disconnectNotify():
- disconnectNotify() is not called when the signal is disconnected
using the QObject::disconnect(QMetaObject::Connection) overload.
- disconnectNotify() is not called when a receiver is destroyed
(i.e., when a connection is implicitly removed).
The old versions of connectNotify() and disconnectNotify() are kept
for now, and they are still called. They will be removed once known
existing reimplementations (e.g., QtNetwork, QtDBus) have been
ported to the new API.

Given a member function that's a signal, returns the corresponding
QMetaMethod. Inspired by the implementation of the template-based
QObject::connect().
The primary use case for this function is to have an effective and
exact (not subject to shadowing) way of checking whether a known
signal was connected to in reimplementations of
QObject::connectNotify(QMetaMethod), avoiding string comparisons.
Example:
void MyObject::connectNotify(const QMetaMethod &signal)
{
if (signal == QMetaMethod::fromSignal(&MyObject::mySignal)) {
// Someone connected to mySignal ...
}
}

QMetaObjectExtraData was added when support for QMetaObject::newInstance
was added. One needed a place to put the pointer to static_metacall in
the QMetaObject.
But as we break binary compatibility, one can change the size of
QMetaObject, and put everything back inside QMetaObject's own structure.
Meaning it is not required anymore to have one QMetaObjectExtraData
instance per QMetaObject anymore.

This is done in preparation of introducing the

forthcoming QMetaMethod::fromSignal() function, which returns the
QMetaMethod corresponding to a Qt/C++ signal (member function), the
comparison operators provide an effective way of checking which
signal was connected to.

It is an extension coming from the use case when you, for instance, need to
implement a countdown timer in client codes, and manually maintain a dedicated
variable for counting down with the help of yet another Timer. There might be
other use cases as well. The returned value is meant to be in milliseconds, as
the method documentation says, since it is reasonable, and consistent with the
rest (ie. the interval accessor).
The elapsed time is already being tracked inside the event dispatcher, thus the
effort is only exposing that for all platforms supported according to the
desired timer identifier, and propagating up to the QTimer public API. It is
done by using the QTimerInfoList class in the glib and unix dispatchers, and the
WinTimeInfo struct for the windows dispatcher.
It might be a good idea to to establish a QWinTimerInfo
(qtimerinfo_win{_p.h,cpp}) in the future for resembling the interface for
windows with the glib/unix management so that it would be consistent. That would
mean abstracting out a base class (~interface) for the timer info classes.
Something like that QAbstractTimerInfo.
Test: Build test only on (Arch)Linux, Windows and Mac. I have also run the unit
tests and they passed as well.

Callers should just call the standard allocation functions directly.
Adding an extra function call onto all basic memory management for the sake of
making it instrumentable in rare cases isn't really fair to everyone else.
What's more, this wasn't completely reliable, as not everything was using them
in a number of places. Memory management can still be overridden using tricks
like LD_PRELOAD if needed.
Their aligned equivilents cannot be deprecated, as no standard equivilents
exist, although investigation into posix_memalign(3) is a possibility
for the future.
