Up to and including meta-object revision 6, string data have been
stored as 0-terminated C-style strings, that were made directly
accessible as const char pointers through the public API
(QMetaMethod and friends).
This commit changes moc to generate an array of QByteArrayData
instead, and adapts the QObject kernel accordingly.
Generating an array of QByteArrayData (byte array literals)
means that the strings can now be returned from public (or private)
API as QByteArrays, rather than const char *, with zero allocation or
copying. Also, the string length is now computed at compile time
(it's part of the QByteArrayData).
This commit only changes the internal representation, and does
not affect existing public API. The actual (C) string data that the
byte array literals reference still consists of zero-terminated
strings. The benefit of having the QByteArrayData array will only
become apparent in the upcoming meta-object data format change, which
changes the format of property and method descriptors.
Support for the old meta-object string data format was kept; the
codepaths for old revisions (6 and below) will be removed in a
separate commit, once all the other meta-object changes are done and
affected code has been adapted accordingly.

Commit aee1f6cc413f56bf4962324799ee3887c3dd037f changed the values of
some built-in meta-type ids. Since the ids of built-in types are
directly encoded -- not as the symbolic QMetaType::Type name, but as
a raw integer -- in the flags for meta-properties, the moc output
prior to that change is incompatible with the current output.

moc can now embed meta information about the plugin
inside the plugin itself. This information can
be queried by Qt without having to load the plugin.
Source compatibility with the old plugin loading
mechanism is still there, but will be removed before
Qt 5.0.

As in the past, to avoid rewriting various autotests that contain

end of the license text to ensure that this commit does not change the
total number of lines in the license header.

The tr() methods are unrelated to the "meta" part, so disabling them
with that macro is not the proper way. They were originally included to
make static checks for string translation simpler, but it just results
in duplicating the definition every time QT_NO_META_MACROS is used.

This patch makes it possible to disable the definition of meta-object
related macros like SIGNAL, Q_SIGNALS, etc. This changes makes it
possible for tools to define the macros in a way that can be used with
them.

This hack was there because symbian used to have a problem with
relocations in the data section, between libraries. Hence, this was needed
so the metaobject could have a pointer to the base metaobject, despite
being in another library.
Anyway, I was told that symbian was fixed eventually. but the hack had to
stay there because of compatibility. But now that we don't even support
symbian, we can get rid of this hack totally.

QWeakPointer is superior and preferred.
Remove QMetaObject::addGuard(), QMetaObject::changeGuard(),
QMetaObject::removeGuard(), and QObjectPrivate::clearGuards().
Implement QPointer using QWeakPointer<T> instead. This changes the
behavior of QPointer in 2 ways:
- During destruction of a QWidget. Previously, the destructor of QWidget
would reset all QPointers so that they would return zero when destroying
children. Update tst_QPointer to account for this change.
- When constructing a QSharedPointer to take ownership of an object
after a QPointer is already tracking the object. Previously, the shared
pointer construction would not be affected by the QPointer, but now
that QPointer is implemented using QWeakPoiner, constructing the
QSharedPointer will cause an abort(). Fix tst_QSharedPointer by
removing the use of QPointer in the objectCast() test.
These behavior changes are documented in the QPointer class
documentation and in the changes file.

The overloads taking a range were previously used for cloned signals
(ones that had default arguments). Commit
919b723088b8617b202b92d80b8d0983e4fd9500 changed how cloned signals are
handled, making the from,to overloads obsolete.
The 3 argument activate() overload that does not take a QMetaObject
argument was marked obsolete by the same commit, but considering that it
is used by our autotests, I've decided to keep it and not mark it as
obsolete anymore.

In addition to the old connection syntax, you can now connect using function pointers.
connect(sender, &Sender::valueChanged,
receiver, &Receiver::updateValue );
You can connect also to functor or C++11 lambdas
The connections are now type safe (no more problems with namespaces
or typedefs). Implicit type conversion is also supported.
The new syntax forces us to change the meaning of signal form
protected to public, in order to be able to access the signal's
address everywhere
The way it works is by introducing new overload of QObject::connect
that take function pointer as parametter. Those new overload are template
function, that are implemented inline. The actual implementation is
in QObject::connectImpl which take a QObject::QSlotObject* as parametter
for the slot. That slot object contains a virtual function which call
the slot which has to be implemented in the header as it depends on the
template parametter. So the internals of QObjectPrivate::Connection
will store this QObjectSlot* in order to be able to make the call.

(The discussions on the mailing list were about trying to find a
solution that do not need making signals public, but no user friendly
solution was found)
Note: support for QueuedConnection, and the symetric QObject::disconnect is
added in another commit.
Qt::UniqueConnection is not supported yet in the new overload.

From a bool to a handle to to connection.
Also added a new overload of disconnect that disconnect a handle
This is required because with the new syntax taking lambda or functors,
it is the only way to disconnect a connection (as it is impossible to
compare functors)
The new return value is QMetaObject::Connection, it is a wrapper around
the internal QObjectPrivate::Connection.
QObjectPrivate::Connection is now reference counted.
tst_qglobal.cpp:
This test set up an internal callback, and the callback do not set any
proper connection handle (and tbh, it would be hard for it to do so).
So the returned QMetaObject::Connection is invalid, and ok is false
(Internal callbacks are only used for jambi and should probably be removed)
