player: simplify OSD message handling code
Eliminate the remains of the OSD message stack. Another simplification comes from the fact that we do not need to care about time going backwards (we always use a monotonic time source, and wrapping time values are practically impossible). What this code was pretty trivial, and by now unnecessarily roundabout. Merge get_osd_msg() into update_osd_msg(), and add_osd_msg() into set_osd_msg_va().
