add gsm0808_cell_id_to_list()
The idea is to be able to add a gsm0808_cell_id to a gsm0808_cell_id_list2: first convert it to a list, then re-use gsm0808_cell_id_list_add(). It will be used by osmo-bsc to manage neighbor-BSS cell identifiers from VTY. Change-Id: Ibf746ac60b1b1e920baf494b396658a5ceabd788
