TX and ReTX should be faster now (for RLC AM, UM and TM). RLC AM Status (function nr_rlc_entity_am.c:status_size()) was not modified, so its CPU usage is the same as before. (It's more complicated to change than for TX and ReTX.)
Initial implementation. nr_rlc/nr_rlc_oai_api.c will need some clean rewrite at some point. More testing is also needed.
