This change adds a new method to QDBusServer to allow anonymous
connections. This is part of the DBus API and was not yet possible
to use with QDBusServer. It is set in the newConnection callback
when a new client tries to connect.
Anonymous connections are enabled by default in DBus but not allowed
by default.
[ChangeLog][QtDBus][QDBusServer] Added method to QDBusServer to allow
anonymous client connections, even if the connecting client is not
authenticated as a user.

The meta-call convention for reading properties differs between Qml and QDBus.
QML expects only to provide a pointer to the return value in args[0]. That is
also how the metacall was originally introduced in Qt 4. QDBus also expects
that the caller allocates a QVariant and provides a pointer to it in a[2], in
addition to a[1] being a pointer to an int that is used to report where the
return value can be found (in where a[0] points to or the variant in a[1]) -
this is useful to report errors when reading the property by clearing the
variant.
For performance reasons, QML avoids the creation of a QVariant when reading
properties. As however QDBus expects it, a crash occurs.
This patch changes the QDBus metacall implementation to not rely on the caller
to provide a QVariant.

Unlike in regular connection to DBus server, we don't get pending call

Thus, we need to keep track of pending calls in such cases and get rid of

QHash::key() is O(n) and we're calling it n times. That can make repeated
calls to the meta object builder very slow, as for example QQmlPropertyMap
when inserting properties repeatedly.
Fortunately this is easy to fix, as the value in the hash map is also the
index, so we can simply iterate over the hash once. With the exception of
the class name, which we have to treat specially to ensure that it is always
the first entry in the string table.

Normally, searching for a V in a container of T using std::lower_bound
only needs an operator<(T,V). But in MSVC2008 debug mode, STL algorithms
perform some extra checks, such as ensuring the range passed to
std::lower_bound is sorted. This adds a requirement for operator<(T,T)
and operator<(V,T).
QtDBus didn't compile on MSVC2008+Debug since 1e37d854 (Sept 2012!)

Copying objects in the tree is not free, but it's not expensive enough
or used frequently enough to justify that error-prone logic. It's much

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.

Several modules, including DBus, MySQL, and OpenSSL have
configure options of the form <MODULE>_PATH, which is used
on Windows (where pkg-config is not present) to specify the
locations of third-party libraries. These switches had been
implemented by adding extra variables which were referenced
in .pro files, to add the appropriate compiler and linker
switches. This is undesirable because it means there are
two independent paths for adding the switches to the build,
which can get out of sync with each other, and indeed this
had happened for some of the DBus tools.
To remedy the situation, all three of the switches were
reworked so that they added values directly to the principal
variables that are used in the project files. This reduces
maintenance, by ensuring that the pkg-config and non-pkg-config
paths appear the same to the rest of the build system.

This test checks whether disconnecting from voidSignal() to our test
receiver will also disconnect from exitLoop(). If it does, we'll get a
timeout. I could have implemented it with two receivers, but in the
buggy case, it would always fail first in the timeout verification.
