Extend RTP frame sending API
Add osmo_rtp_send_frame_ext() which accept boolean parameter in addition
to arguments of osmo_rtp_send_frame() to explicitly set marker bit in
RTP header. Previously it was always unset which resulted in degradation
of speech quality for codecs with explicit talkspurt events (was tested
with AMR's ONSET).
