8b6f8d66ec tests: removed QtWidgets dependency from tst_qsignalmapper
This test was using some QSpinBox instances to generate signals for
testing. Use our own QtTestObject to generate the signals instead.

e083d25395 QMetaTypeId2::IsBuiltIn: (new) template meta-function to check for built-in types
This allows to check whether QMetaTypeId2::MetaType exists, and can help
turn run-time into compile-time expressions, even without constexpr support,
or in situations where constexpr can't be used (because you can't overload
on it). This was designed for the QMetaType::registerConversion feature,
but it's much more widely applicable.

d359b0af2b Call QObject::disconnectNotify() when receiver is destroyed
Store the signal index in QObjectPrivate::Connection, thereby making
it available in "implicit" disconnect contexts (i.e., receiver
deletion).

This change does not cause the size of QObjectPrivate::Connection
to grow (still 40 bytes on 32-bit Linux, 72 bytes on 64-bit Mac).

Valgrinding the new benchmark indicates that the percentage of the
time spent in the QObject destructor increased from 7.8% to 8.4%
on ia32, for that particular stress test; the increase is the
combined cost of calling metaObject(), QMetaObjectPrivate::signal(),
and disconnectNotify() for one connection. In practice, the measured
wallclock time increased by about 3ms for a 500ms run (which
repeatedly constructs, connects, and destroys an object).

32bc019ac1 Fix automatic declaration of QSharedPointer<T> metatypes.
QSharedPointer doesn't work like the other automatic template metatype
declarations because in some cases T* is declared as a metatype, but we
are interested in QSharedPointer<T> (eg QObject*). In other cases, T is
declared as a metatype and we are interested
in QSharedPointer<T> (eg char).

In particular the macro used before this patch was attempting to get the
metatype id of the element_type using for example qMetaTypeId<QObject>()
instead of qMetaTypeId<QObject*>(), which did not work.

Similarly, the variadic macro driven test is no good, because it was
testing QSharedPointer<QObject*> instead of QSharedPointer<QObject>,
so that is removed.

In the end, the only thing we can sensibly automatically declare as
metatypes are QSharedPointers to QObject derived types. That is also
the type that makes the most sense in a QML context anyway.

37db43f1c2 Add private API for working with meta-methods in signal index range
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.

74c3517e6a Fix regression in connectNotify(const char *) emission
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.

40a73d7c63 Fixed uninitialized memory in QMetaObjectBuilder::fromRelocatableData
static_metacall was never set on the metaobject written by
QMetaObjectBuilder::fromRelocatableData, sometimes causing a crash.  It
should be initialized to 0.

243ea09e4c Add QMetaMethod-based QObject::connect/disconnectNotify() API
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.

dac23b9a57 Add QMetaMethod::fromSignal() function
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 ...
    }
}

67f58040ea Remove QMetaObjectExtraData and put everything into QMetaObject
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.
