[M] Change in osmo-mgw[master]: E1: change dummy fill frame generation method

Attention is currently required from: falconia. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-mgw/+/39750?usp=email to look at the new patch set (#3). The following approvals got outdated and were removed: Verified-1 by Jenkins Builder Change subject: E1: change dummy fill frame generation method ...................................................................... E1: change dummy fill frame generation method In the absence of a proper TFO transform (TS 28.062 section C3.2.1.1), OsmoMGW-E1 inserts constant fill frames when there is no RTP input, or when RTP input fails conversion to TRAU-DL and thus does not enqueue anything to the I.460 mux. (We accept TW-TS-001 and TW-TS-002 from RTP side, but bad frames cannot be converted to TRAU-DL without a TFO transform.) Prior to the present change, this idle fill of the DL was done using fully hard-coded frames, i.e., the operation of converting the desired fill to TRAU-DL bit format was done once externally and the raw bit frames were hard-coded. Change this approach: use fill frames in RTP format provided by libosmocodec, and execute osmo_rtp2trau() followed by osmo_trau_frame_encode() in the fill frame output path just like we do for regular RTP to DL.
