"no signature" is misleading and even led me to re-check the code to see
if it meant that the reply failed and no signature could be obtained.
Saying that the signature was obtained but is empty is better.

Most of QtDBus already needs very little from libdus-1, so create an
extra header containing the minimum API we actually need.
One large advantage of this solution is that now QtDBus can always be
enabled, even if the system doesn't have libdbus-1 installed. This is
interesting on OS X, where libdbus-1 is often installed by Homebrew or
MacPorts, which may include extra libraries we don't want in our
packaging.

QDBusMessage is intended to avoid sending reply messages unless
the message is a method call without the NO_REPLY_EXPECTED flag set.
However, since messages which are not method calls will never have
this flag set, the code will currently cause all non-method call
messages to expect a reply. This patch changes the code to examine
the message type, and to only check for the flag in cases where the
message is a method call.

We don't need two anymore because they now protect the same thing: the
state of the DBusConnection. The difference existed when it was possible
for two threads to access the DBusConnection at the same time: one doing
dispatching and one doing something else. Unfortunately, even though
DBusConnection supports this, QtDBus doesn't.
From d47c05b1889bb4f06203bbc65f4660b8d0128954 (2008-10-08):
Details: if we're removing a timer or a watcher from our list,
there's a race condition: one thread (not the QDBusConnection thread)
could be asking for the removal (which causes an event to be sent),
then deletes the pointer. In the meantime, QDBusConnection will
process the timers and socket notifiers and could end up calling
lidbus-1 with deleted pointers.
That commit fixed the race condition but introduced a deadlock.

Blocking DBus calls have the potential to totally wreck user interactivity at
best (actions taking too long) and make things appear completely broken at worst
(the default timeout is 30 seconds, which is a huge amount of time, especially
if you get unfortunate and have a repeated blocking call).
Provide a warning when a call is found that takes too long, based on some preset
durations (200ms for the main thread, 500ms for other threads on the basis that
the main thread is generally more important).
Also provide configuration knobs for these environment variables, in miliseconds:
setting them to 0 will warn on all blocking DBus calls. Setting them to -1 (the
default, on release builds) will disable the warning.
[ChangeLog][QtDBus] Blocking calls that take a long time will now generate a
warning. The time taken may be tuned using the environment variables
Q_DBUS_BLOCKING_CALL_MAIN_THREAD_WARNING_MS and
Q_DBUS_BLOCKING_CALL_OTHER_THREAD_WARNING_MS. The value represents (in
milliseconds) how long before a blocking call is warned on. A value below zero
disables the warning, a value of zero will warn on all blocking calls.

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.

Fortunately this is easy to fix, as the value in the hash map is also the

the class name, which we have to treat specially to ensure that it is always
the first entry in the string table.
