21d7ce97c3 GDBus: plug some memory leaks
These fixes makes udisks-daemon from udisks' gdbus-port branch, see

 http://cgit.freedesktop.org/udisks/log/?h=gdbus-port

handle 200 add/remove uevents generated by e.g.

 #!/bin/bash
 DEV=mmcblk0p1
 for n in `seq 200` ; do
     udevadm trigger --sysname-match=$DEV --action=remove
     udevadm trigger --sysname-match=$DEV --action=add
     echo foo $n
 done

without any substantial leaks.

79d32c2fc1 GDBusMessage: Fix bug when deserializing a message
See https://bugzilla.gnome.org/show_bug.cgi?id=621838 for the whole
story. The problem was that we ended up reading data from arrays of
arrays when we were just supposed to be aligning the buffers.

Also add a host of debug infrastructure that was needed to find the
root cause. For now it can be turned on only via defining
DEBUG_SERIALIZER. In the future we might want to make it work via
G_DBUS_DEBUG. In a nutshell, the added debug info looks like this

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.

bb6530eb34 GDBus: Fix serialization of empty arrays
It turns out that we didn't observe padding (neither when reading nor
writing) for empty arrays which (apparently) is needed according to
the D-Bus spec and reference implementation. A simple test case to
provoke this behavior is as follows (notice the lack of 4 bytes worth
of padding at position 0x0064):

 Error calling dbus_message_demarshal() on this blob: org.freedesktop.DBus.Error.InvalidArgs: Message is corrupted (Alignment padding not null)

 0070: 74 68 69 6e  67 00                                    thing.

 The blob was generated from the following GVariant value:
 ('01234567890123456', @a{sv} {}, ['Something'])

 If the blob was encoded using DBusMessageIter, the payload would have been:
