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). Create a new OSMO_GSUP_MSGT_E_ROUTING_ERROR message type, which the GSUP server uses to tell a client that its message could not be forwarded to the destination (see [1]). MAP has no related message. [1]: Change-Id: Ia4f345abc877baaf0a8f73b8988e6514d9589bf5 (osmo-hlr.git) Related: OS#3774 Change-Id: Ic00b0601eacff6d72927cea51767801142ee75db
