[M] Change in libosmo-abis[master]: trau: new function osmo_trau2rtp_ufe()

Attention is currently required from: falconia, fixeria. Hello Jenkins Builder, fixeria, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-abis/+/39731?usp=email to look at the new patch set (#2). The following approvals got outdated and were removed: Code-Review+1 by fixeria, Verified+1 by Jenkins Builder Change subject: trau: new function osmo_trau2rtp_ufe() ...................................................................... trau: new function osmo_trau2rtp_ufe() TRAU frame formats for newer codecs (HR, EFR, AMR) include a UFE (uplink frame error) indicator bit in the DL direction. TRAUs are expected to set this bit to active error state (0 for HR/EFR/AMR or 1 for D144 E-TRAU) if frame synchronization is lost in the UL direction, or if received TRAU-UL frames have bad CRC or invalid control bits - errors that indicate corruption on terrestrial circuits or faults in the CCU, rather than radio Rx errors. In Osmocom implementation, TRAU frame CRC and control bit patterns are checked during conversion to RTP, as part of the work done by osmo_trau2rtp() - but there is no separate return indication from that function that distinguishes these errors from ordinary BFIs due to radio errors or FACCH stealing etc. Solution: add a new API function that indicates UFE conditions separately.
