Thiago Macieira d370878aa0 Fix undefined behavior: accessing an object after destruction
QDBusConnectionPrivate keeps a pointer to a QDBusConnectionInterface,
which in turn holds a reference back to that QDBusConnectionPrivate.
During the interface object's destruction, the QDBusAbstractInterface's
destructor checks if the interface is still valid. That access is
undefined behavior, but has so far been benign in all our uses since
the memory had not yet been freed (just destroyed) and the reference
count went from 0 to -1.

To be on the safe side, we destroy now the QDBusConnectionInterface
object while the Private is still valid. It will bring the reference
count down from 0 to a negative number, but won't cause any other
effects.

Thiago Macieira 2bcbe227bd Fix crashes on shutdown when the D-Bus spy list has been destroyed
The QDBusConnection spy hook is most often created after the
QDBusConnectionManager global, which means it will get destroyed before.
That means we'll almost surely going to get a null pointer dereference
if we handle the socket close to shutdown.

Alberto Mardegan 748abf9347 Add QDBusMessage::createTargetedSignal()
The QDBusMessage::createSignal() static method doesn't take a parameter
for specifying the destination service of the signal. While this is not
a widely used feature, it can be useful to avoid waking up all connected

in the signal.

also takes the destination service as its first parameter.

Unfortunately, other names like "dbus-1.dll" have been seen in the wild,

prefix). Both basenames work on Unix, so give "libdbus-1" on Unix since
that will result in one fewer stat.

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.

Albert Astals Cid e4eb9bfbf7 Break after handling the read/write
The loop is there because watchers may have two Watcher for the same
fd, one for read and one for write, but after we're processed the
correct one we don't need to keep looping.

This fixes a crash since it's possible that while in processing
q_dbus_watch_handle we get a watch added/remove this invalidating
the iterator and crashing

Matt Fischer cd2ac1e2e5 Don't send reply messages for non-method calls in QDBusMessage
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.

Thiago Macieira 73a1e8c60d Partially revert "Fix a deadlock introduced by the race condition fix"
The commit was 9361be58f47ec256bf920c378479a02501219c1f (2008-11-17),
referring to the race condition fix that was applied in commit
d47c05b1889bb4f06203bbc65f4660b8d0128954 (2008-10-08). The fix for the
deadlock reintroduced the race condition and the commit message noted
it.

The workaround is no longer necessary since we've fixed the original race
condition differently now (see the previous two commits).

Thiago Macieira eb99c28861 QDBusConnection: Merge the dispatch and the watch-and-timeout locks
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.
