[S] Change in libosmocore[master]: coding: fix artificial bit errors for PDTCH CS2 and CS3

by fixeria

fixeria has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/35754?usp=email ) Change subject: coding: fix artificial bit errors for PDTCH CS2 and CS3 ...................................................................... coding: fix artificial bit errors for PDTCH CS2 and CS3 GPRS coding schemes CS2 and CS3 (defined in 3GPP TS 45.003 sections 5.1.2 and 5.1.3, respectively) employ so-called puncturing, which can be described as intentional removal of coded bits. The goal of puncturing is to reduce the number of coded bits, so that they fit into 4 bursts. The receiving side recovers punctured bits, as if they were received corrupted. The puncturing is also used for other channel types like TCH/F9.6, TCH/F14.4, TCH/AFS and TCH/AHS, but only for CS2 and CS3 we're doing puncturing/depuncturing *manually*. This explains why we're seeing artificial bit errors only for CS2 and CS3. gsm0503_pdtch_decode() should not be reporting punctured bits as bit errors, fix this by using osmo_conv_decode_ber_punctured().
