support for more cell ID list types in libosmocore
Introduce gsm0808_dec_cell_id_list2() with supports additional types of
cell identifier lists. The new parsing routines are based on similar
routines used by the paging code in osmo-bsc's osmo_bsc_bssap.c.
Likewise, introduce gsm0808_enc_cell_id_list2() with support for the
same additional types of cell identifier lists.
The old API using struct gsm0808_cell_id_list is deprecated.
The previous definition was insufficient because it assumed that all
decoded cell ID types could be represented with a single uint16_t.
It was declared in a GSM protocol header (gsm/protocol/gsm_08_08.h)
despite being a host-side representation of data in an IE.
The only user I am aware of is in osmo-msc, where this struct is used
for one local variable. osmo-msc releases >= 1.1.0 make use of this API.
While here, fix a small bug in a test:
test_gsm0808_enc_dec_cell_id_list_bss() set the cell ID type to 'LAC'
but obviously wants to use type 'BSS'.
