[PATCH] libosmo-abis[master]: Extend osmo_rtp_send_frame API

[Max]

Review at  https://gerrit.osmocom.org/82

Extend osmo_rtp_send_frame API

Add boolean parameter to 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).
