[Florian Müllner <fmuellner src gnome org>]

commit 1a549bf81808704dce2fb23012c33e35b77b2346

    lib: Add PolariMessage type
    
    We have used a small message object to abstract differences between the
    telepathy-glib and telepathy-logger message types ever since we started
    to include backlogs. So far we just used a plain JS object, however we
    will soon need to represent messages in C code as well, so add a new
    boxed type that can replace the existing intermediate object.
    This will promote the existing telepathy-logger dependency from runtime-
    to build-time dependency, however this is temporary and we will soon get
    rid of the dependency altogether.
