Merge branch 'anders/diameter/codec/OTP-14511' into maint
* anders/diameter/codec/OTP-14511: (26 commits) Limit SCTP testing in traffic suite Increase init_per_group timetrap in traffic suite Add diameter_util:eprof/1 for test Don't search forms unnecessarily in diameter_exprecs parse transform Increase init_per_suite timetrap in traffic suite Don't count AVPs unnecessarily at encode Test decode_format record_from_map in traffic suite Tweak limiting of testcases in traffic suite Don't take length of AVP lists unnecessarily at encode Tweak map-valued decode Rearrange group names in traffic suite Randomly wrap answers in diameter_packet in transport suite Don't exercise client/server encoding independently in traffic suite Add decode_format record_from_map Rename record_decode -> decode_format Create fewer client connections in traffic suite Test record_decode in traffic suite Map answers to maps in traffic suite Test map encoding in traffic suite Let messages and grouped AVPs be decoded to lists ...
