dbus 1.2.22

[Colin Walters]

A new release of dbus is available.

http://dbus.freedesktop.org/releases/dbus/dbus-1.2.22.tar.gz

The focus of the 1.2 stream remains mainly reliability fixes, while
win32 (and Windows CE now, scary!) porting and feature work is on 1.3,
scheduled for 1.4 stable.

Before the shortlog, let me highlight the two most important patches.
First, from Michael Meeks, is

Michael Meeks:
      [DBusConnection] When handling a watch, return if another thread
is doing I/O

This fix is pretty important for avoiding UI freezes in newer
Evolution versions (and any other program that makes synchronous DBus
calls from a non-main thread).  So this version of DBus is highly
recommended for shipment with GNOME 2.30.

The other one is a more embarrassing bug:

Colin Walters:
      Monitor service directories for changes

We never watched for changes in the services/ directory, so if you installed a
new app or component using DBus, most of the rest of the stack would
automatically
work (.desktop files, etc.) , but dbus wouldn't find the .service
until it was manually sent SIGHUP.

So two important fixes.  The shortlog follows:
