aab6d9ed1c GDBus: Handle autolaunching on UNIX/Freedesktop OSes
Also add a 'address' G_DBUS_DEBUG option that will print out useful
debug information such as

Note that things work exactly like libdbus, e.g. from the
dbus-launch(1) man page:

  Whenever an autolaunch occurs, the application that had to start a
  new bus will be in its own little world; it can effectively end up
  starting a whole new session if it tries to use a lot of bus
  services. This can be suboptimal or even totally broken, depending
  on the app and what it tries to do.

  [...]

  You can always avoid autolaunch by manually setting
  DBUS_SESSION_BUS_ADDRESS. Autolaunch happens because the default
  address if none is set is "autolaunch:", so if any other address is
  set there will be no autolaunch. You can however include autolaunch
  in an explicit session bus address as a fallback, for example
  DBUS_SESSION_BUS_ADDRESS="something:,autolaunch:" - in that case if
  the first address doesn't work, processes will autolaunch. (The bus
  address variable contains a comma-separated list of addresses to
  try.)

366b3ffcde Bug 619142 – Build fixes
- Fix various #include issues

 - Change #error to #warning for the EXTERNAL authentication mechanism.
   It is not clear if this should work on Win32 at all.

 - Call close() before unlink() for the SHA1 keyring

 - Change #error to #warning so we don't forget to do
   permission checking of the .dbus-keyrings directory

 - Use Win32 SID for the SHA1 auth mech

 - Apparently we can't use word 'interface' as an identifier

 - Implement a _g_dbus_win32_get_user_sid() function. For now it's
   private. Don't know if it should be public somewhere. Maybe in
   a future GCredentials support for Win32? I don't know.

 - GFileDescriptorBased is not available on Win32. So avoid using
   it in GLocalFile stuff. Now, Win32 still uses GLocalFile + friends
   (which works with file descriptors) so expose a private function
   to get the fd for an OutputStream so things still work.

 - Fixup gio.symbols

 - Fixup tests/gdbus-peer.c so it builds

With this, at least things compile and the gdbus-peer.exe test case
passes. Which is a great start. I've tested this by cross-compiling on
a x86_64 Fedora 13 host using mingw32 and running the code on a 32-bit
Windows 7 box.

d0a14469d0 Initial GDBus code-drop from GDBus-standalone repo
Things compile and the test-suite passes. Still need to hook up
gio.symbols and docs. There are still a bunch of TODOs left in the
sources that needs to be addressed.
