[M] Change in osmo-ttcn3-hacks[master]: library/s1ap: rework {ts,tr}_S1AP_RABSetupRsp templates

Our templates for this S1AP PDU require the former to be a value (as if it was mandatory) and do not allow passing the later.

[S] Change in osmo-sgsn[master]: Refactor diffing same GMM messages

by lynxis lazus

lynxis lazus has submitted this change. ( https://gerrit.osmocom.org/c/osmo-sgsn/+/37867?usp=email ) ( 19 is the latest approved patch-set. No files were changed between the latest approved patch-set and the submitted one. )Change subject: Refactor diffing same GMM messages ...................................................................... Refactor diffing same GMM messages gprs_gmm_attach_req_ies() isn't specific for the attach request. It also did not cover the full message because of a fixed message length when comparing both messages. A diff of the old and new GMM message is required to figure out if the MS/UE is retransmitting an old message or starting a new procedure.
