Fixes race between QDBusConnectionPrivate::processFinishedCall()
releasing the mutex before emitting signals (using various members of
QDBusPendingCallPrivate) and deletion of the QDBusPendingCallPrivate
object through QDBusPendingCall::d's destructor (a member of type
QExplicitlySharedDataPointer<QDBusPendingCallPrivate>) leeds to
segmentation fault with CrashTest example on slow/single core
arm cpu).

First step to fix race condition about deleting QDBusPendingCallPrivate.
In a multithreaded application on a slow/single core cpu the following
race (and segmentation fault) can occur:
First thread A is running:
A: QDBusPendingReply<> reply = pi->asyncCallWithArgumentList(method, argumentList);
Then when the dbus answer arrives thread B will call:
B: QDBusConnectionPrivate::processFinishedCall()
B: ...
B: locker.unlock()
and runs until here, go on with thread A:
A: reply.waitForFinished();
A: QDBusPendingCallPrivate::waitForFinished()
A: {
A: QMutexLocker locker(&mutex);
A: if (replyMessage.type() != QDBusMessage::InvalidMessage)
A: return;
which returns immediately (mutex acquired, replyMessage alread set), now
reply goes out of scope (destructor called) and QDBusPendingCall::d's
destructor of type QExplicitlySharedDataPointer<QDBusPendingCallPrivate>
deletes the reference counted object QDBusPendingCallPrivate.
Now thread B continues, still in processFinishedCall()
B: if (call->watcherHelper)
B: call->watcherHelper->emitSignals(msg, call->sentMessage);
B:
B: if (msg.type() == QDBusMessage::ErrorMessage)
B: emit connection->callWithCallbackFailed(QDBusError(msg),
B: call->sentMessage);
accessing alread deleted object QDBusPendingCallPrivate via call->...
Fixed QDBusPendingCallPrivate deletion by proper reference counting
will be done in the next commit.

In QDBusConnectionPrivate::waitForFinished() pcall->pending was used
after the protection by pcall->mutex was released. A simultaneous
call to QDBusConnectionPrivate::processFinishedCall() was able
to reset pcall->pending to null before it was used for the
q_dbus_pending_call_block(pcall->pending) call.
Fixed by releasing (and setting to 0) of pcall->pending in
processFinishedCall() only in case no one is waiting yet, otherwise
release pcall->pending by the first thread waiting in waitForFinished().
There is still a race condition about deleting QDBusPendingCallPrivate
(too early) which will be fixed in the next two commits.
