MMS integration.

Very experimental.
Fixed signal signatures, added more debug trace
Tweaking packing/unpacking of message parts
Removed unnecessary annotation
Decoding QDBus arguments
Hooking up notifications
Use /org/freedesktop/Telepathy/Account/ring/tel/account0 as local uid
No need for both uuid and message id
Set LastPart attribute for the last attachment
Fixed signal signature (again)
MMS integration (experimental)
Separate system bus interface for MMS

When MMS backend is auto-started by ofonod it doesn't have access to the
session bus (it might be possible with some hacking but not out of the box).
The easiest way around it is to do all the MMS D-Bus communication over the
system bus. And it even makes certain amount of sense since MMS is a system
service and there's nothing session specific about it.
Merge branch 'mms-test' into slava-mms-devel
Enable debug trace in debug build
Tweaking D-Bus interface with MMS backend
Merge branch 'master' into slava-mms-devel
mmsReceived is no more
Minimize differences with trunk
Took out unnecessary MmsService instance
