libosmo-tlv: add auto dec/enc to/from structs

Add osmo_tlv_coding: describe the value part of a TLV (decode and encode), describe a struct with its members, and get/put readily decoded structs from/to a raw PDU, directly.

With osmo_tlv_coding defined for a protocol's tags, we only deal with encoded PDUs or fully decoded C structs, no TLV related re-implementations clutter up the message handling code.

A usage example is given in tlv_dec_enc_test. The first real use will be the PFCP protocol in osmo-upf.git.

With osmo_tlv_coding, there still is a lot of monkey work involved in describing the decoded structs. A subsequent patch adds a generator for osmo_tlv_coding and message structs from tag value lists.
