sync tools/ with telepathy-glib This should allow Empathy to be build with Python 3. https://bugzilla.gnome.org/show_bug.cgi?id=687616
sync tools/* with tp-glib master Fix extensions/Makefile.am to build with the new tools.
Import tools from telepathy-glib 0.7.3 and build a static libemp-extensions.la. Link that library into libempathy (it's not actually used for anything at this point). Extensions currently built: ChannelHandler and StreamEngine. The namespacing convention used is emp_*, Emp*, EMP_* so it won't be included in the library ABI. svn path=/trunk/; revision=663
