gsup: Introduce OSMO_GSUP_NUM_VECTORS_REQ_IE
This is a bit of a hack, as we want to maintain binary compatibility
without breaking existing users of libosmocore. To do so, we use the
'num_auth_vectors' field in two ways now:
* In the existing use case as part of SEND_AUTH_INFO_RESPONSE, it
indicates the number of vectors stored in the 'auth_vectors' field
* In the new use case as part of SEND_AUTH_INFO_REQUEST, it indicates
the number of vectors actually requested by the MSC/SGSN/MME.
