[M] Change in libosmocore[master]: ns2: Count transmitted/dropped in each layer implementation

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/32535 ) Change subject: ns2: Count transmitted/dropped in each layer implementation ...................................................................... ns2: Count transmitted/dropped in each layer implementation This allows better control on how the counters are ticked. For instance, since nowadays the writing in ns2_udp is done asyncrhonously, most probable failures occur at a later point and not when returning to the caller.
