deps/Makefile: Update titan.TestPorts.MTP3asp to upstream master
We used to point to an osmocom fork with a commit from 2018 fixing build without MTP3asp_PT.cc/hh. That commit was merged upstream in 2020, so we can point back to upstream.
Use newer M3UA & MTP3 deps generating MTP-STATUS,PAUSE,RESUME.ind
* titan.TestPorts.MTP3asp pointer is changed to osmocom fork containing extra patch adding missing fields to MTP-STATUS,PAUSE,RESUME records. It also adds templates for them. * titan.ProtocolEmulations.M3UA pointer is changed to osmocom fork containing extra patch improving M3UA_Emulation component to build MTP-STATUS,PAUSE,RESUME.ind primiives when receiving DAVA/DUNA/DUPU/SCON from M3UA link.
The upper layers building on top of MTP3asp_PT (ie. port MTP3asp_SCCP_PT from SCCP_MApping.ttcnp) are fine because they explicitly discard ASP_MTP3_PAUSE,RESUME,STATUS messages in the port defintion. Hence, supporting those in SCCP layer is left as a subsequent task.
