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
