add gsm0808_cell_id_from_cgi(), gsm0808_cell_id_to_cgi()
CGI to Cell ID: for example, for Paging, osmo-msc has a CGI for a subscriber and needs to send out a Cell Identifier IE. Makes sense to add this conversion here. Cell ID to CGI: for a Layer 3 Complete, a subscriber sends the current cell in the form of a Cell Identifier, which we store as a CGI, if necessary enriched with the local PLMN. Add enum with bitmask values to identify parts of a CGI, for the return value of gsm0808_cell_id_to_cgi(). Can't use enum CELL_IDENT for that, because it doesn't have a value for just a PLMN (and is not a bitmask). Change-Id: Ib9af67b100c4583342a2103669732dab2e577b04
