RawDBusConnection incorrectly uses detail::RefCounted, which it
shouldn't. This patch converts it to use AtomicRefCounted instead.

Instances of RawDBusConnection can now be contained in nsRefPtr. This
allows to share the DBus connection among multiple threads.

SystemErrorReporter is the new unified error reporter for everything non-dom.
In particular, it's used by the SafeJSContext, which we'll be switching to
here shortly.
We need to stash it somewhere, because the shell-provided JSNatives need to
access it. This solution only works for script running in the scope of the
global we create. Butthat's fine here, because we only use it for load() and
quit(), which only exist in the scope of that global.

The method BluetoothDBusService::GetServiceChannel currently blocks the
Bluetooth command thread while waiting for a DBus message, before it
dispatches a runnable to the main thread.
With this patch, the DBus message is processed asyncronously, and the
runnable gets dispatched from the DBus reply handler.

Handler functions for DBus replies sometimes need several data fields
or need to keep state over replies for multiple messages. The DBus API
itself only allows for a single pointer to user data.
The class DBusReplyHandler is a base class for implementing DBus reply-
message handlers. Users of DBus can inherit from this class to implement
message-specific handlers.

This is a mechanical change made with sed. Later patches in this queue
clean up the whitespace errors and so on.
This stuff shouldn't be necessary anymore. The default security manager should
do the right thing given for script running in the scope of a BackstagePass.
The this commit moves the sending of blocking DBus messages to the
DBus thread. This allows us to avoid concurrency problems within the
DBus library, which is not explicitly thread-safe.
As a side note, I'd like to mention that blocking in distributed
systems simply doesn't work. The dbus library is especially broken
in this regard as it delays all unrelated messages until the reply
for the blocking request has been received. A future commit should
implement this functionality with an asyncronous call and make the
related thread wait for the reply.
The DBus send operation simply sends a DBus message without further
processing of replies. If the sender is interested in a reply, the
respective serial number can be returned. In this case, the sending
operation (and only the sending) is serialized with the calling
thread.
The class DBusConnectionSendWithReplyTask has been renamed to
DBusConnectionSendWithReplyRunnable, which better fits its purpose. The
internal callback function and data has been move into the implementation
of DBusConnectionSendWithReplyRunnable. Additionally, there is now an
abstract base class for DBus send runnables. This class will become useful
for implementing send classes with different policies.
This patch finally fixes bug 827888 were a message's reply was
received before the respective handler function could be installed.
The patch adds the class DBusConnectionSendWithReplyTask, which
asyncronously sends a DBus message and installs the reply's handler
function. The DBus utility functions for asyncronous messages create
an instance of this class and dispatch it to the DBus thread. This
intercepts the DBusPollTask, so no DBus replies can be received until
the dispatched DBusConnectionSendWithReplyTask has finished.
The new function allows to schedule nsRunnables to an existing DBus
thread. This intercepts the running instance of DBusPollTask and
makes the DBus thread process the dispatched runnable. The intercepted
poll task automatically continues polling once all pending runnables
have been processed.
This patch replaces the DBus EventLoop function by an instance
of DBusPollTask. It also cleans up the initialization and shutdown
code of the DBusThread.
This patch adds class DBusPollTask. The DBusPollTask class is an
nsRunnable for receiving DBus messages. It is intended to run in
a separate thread that is dedicated to DBus only.
The Run function of the poll task resembles the DBus EventLoop
function, but allows to intercept execution in favor of other
nsRunnables. Afterwards the DBusPollTask continues.
We intent to run the DBus thread's EventLoop function as separate
nsRunnable, but the function also contains code for initializing
sockets that are used for internal communication.
With this patch the socket initialization has been moved to the
setup function. This reduces the EventLoop function to plain event
handling.
