Change subject: GSUP: add inter-MSC handover related msgs and IEs
......................................................................
GSUP: add inter-MSC handover related msgs and IEs
Based on a draft created by Neels, which is the result of reading a MAP
trace of two MSCs negotiating inter-MSC handovers, and of reading the
TS 29.002, TS 29.010 and related specs:
https://lists.osmocom.org/pipermail/openbsc/2019-January/012653.html
I figured out that the "Handover Number" mentioned in the specifications
is the same as the MSISDN IE that we already have, so we can use that
instead of creating a new IE (example usage in tests/gsup/gsup_test.c).
Related: OS#3774
