add osmo_bssap_tlv_parse2() for multiple identical T
In BSSMAP messages, at least the Cell Identifier IE can appear more than once. We have tlv_parse2() which allows decoding into an array of tlv_parsed to cleanly handle multiple occurences. Hence add osmo_bssap_tlv_parse2() which supports multiple occurences. An alternative would be to directly call tlv_parse2() with gsm0808_att_tlvdef() when multiple T occurences are needed, and I'm not really sure why osmo_bssap_tlv_parse() exists in the first place. But because it does, add a similar definition that is capable of handling multiple IEs with identical Tag discriminator. Change-Id: Ib9a2095f7498dc2cda2a57154b2dbe4621df72f8
