QSharedPointer is about to be made final. Instead
of inheriting from it to gain access to the
d-pointer, cast it to a layout-compatible struct
and access the pointer from there.
Assert liberally to ensure layout compatibility.

QMap used to use a skiplist in Qt 4.x, which has variable
sized nodes and we can thus not optimise using custom
allocators.
The rewrite now uses a red-black tree, and all allocations
and tree operations happen in the cpp file. This will allow
us to introduce custom allocation schemes in later versions
of Qt.
Added some more tests and a benchmark. Memory consumption
of the new QMap implementation is pretty much the same as before.
Performance of insertion and lookup has increased by 10-30%. iteration
is slower, but still extremely fast and should not matter compared
to the work usually done when iterating.

We are running out of type ids for built-in types, 255 is not enough.
QMetaType already contains about ~70 types, situation is maybe not
tragic now, but there is a great chance that we will want to add more
built-in types from different modules like jsondb or declarative. Then
it might be tight, because we are not allowed to reorganize type ids
(it would be a binary incompatible change).
This change was not possible up to now. Old moc generated code assumes
that type id can be safely stored in 8 bits.
This is source compatible change.

For Qt5 we no longer want to support the older revisions due to the
dual codepaths that must be maintained, and because the format of the
meta-object data is quite different in revision 7.
The dual codepaths have been replaced by asserts that indicate the
revision in which the feature was introduced, and the older-revision
fallbacks have been removed.
It's not possible to build code generated by moc that has
revision <= 6 with Qt5 because the type of the
QMetaObject::stringdata member changed from const char * to const
QByteArrayData *. For the same reason it's not possible to build a
dynamic meta-object generator targeting revision <= 6 with Qt5.
Hence, too old meta-objects will be caught at compile time, and the
code will have to be ported to generate revision 7 (e.g., by running
Qt5's moc on the original class declaration).

QMetaMethod::typeName() is documented to return an empty string if
the return type is void. But after the introduction of
QMetaType::UnknownType (where void was made a distinct type),
returning an empty string causes the idiom
QMetaType::type(method.typeName())
to break; the result will be QMetaType::UnknownType rather than
the expected QMetaType::Void for methods that return void.
New code should use the new function QMetaMethod::returnType()
instead, but it would be good if existing code still did the right
thing.
The consequence of returning "void" instead of an empty string is
that it breaks existing logic that uses the typeName() length to
determine whether a method returns void. But we judge this as the
lesser of the two evils; it's better to have a typeName() function
that is consistent and keeps the QMetaType::type(method.typeName())
idiom working, than to force the typeName() inconsistency for void
only to keep code that does "strlen(method.typeName()) == 0"
working.
The places in Qt that were relying on a zero-length typeName()
(testlib, dbus, declarative) have already been changed to use
returnType().
Also adapt QMetaObjectBuilder, which is internal API.

Commit 3fe1eed0 changed the QVERIFY in line 1354 to QCOMPARE. This was
done to work around a (not yet understood) compiler issue. That however
was wrong, as char pointers in QCOMPARE are assumed to point to
'\0'-terminated strings and will get dereferenced.
In this case the intent was to compare the actual pointer values, as the
pointers point past the end of the array and should not be dereferenced.
Explicitly casting to (void *) and using QCOMPARE will not only keep the
intent, it will hopefully also provide meaningful output on failures. As
such the fix was applied throughout the test.

PCRE's JIT uses by default 32K on the pcre_exec caller's stack. This
is fine for most situations, but in some cases (esp. patterns with
lot of recursion) more memory is required.
Therefore, if a match execution fails due to exhausting JIT memory,
we let PCRE allocate up to 512KB to be used for the JIT's stack.
The pointer to the allocated memory is put in thread local storage
(so it can be reused from the same thread, if needed, and automatically
goes away when the thread dies).
