[M] Change in libosmo-abis[master]: osmo_rtp2trau() for FR & EFR: correctly handle the no-data case

Attention is currently required from: neels, laforge. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-abis/+/32078 to look at the new patch set (#2). Change subject: osmo_rtp2trau() for FR & EFR: correctly handle the no-data case ...................................................................... osmo_rtp2trau() for FR & EFR: correctly handle the no-data case 3GPP TS 48.060 sections 6.5.2 and 6.5.3 prescribe the behavior of TRAU frame emitters under conditions of not having any speech or SID frame to send. In the case of osmo_rtp2trau() this no-data condition is indicated with a zero rtp_len argument to the function, but this case was not handled correctly: a garbage speech frame (previous buffer content for the D bits in struct osmo_trau_frame) was being generated. The present change implements the rules of TS 48.060 sections 6.5.2 and 6.5.3: standard FR/EFR speech frame with BFI=1 for DL, special idle speech frame pattern for UL.
