add gsm0808_cell_{id,id_list}_name() and friends
Provide comprehensive API to obtain string representations of Cell Identifiers
and -Lists.
Change gsm0808_test.c to use the new functions (which simplifies the output a
bit), so that we don't duplicate printing code in gsm0808_test.c, and so that
the not-so-trivial printing code is also tested.
In gsm0808_test, also test gsm0808_cell_id_list_name_buf()'s return value and
truncation behavior.
The rationale for gsm0808_cell_id_list_name(), i.e. printing an entire list of
cell identifiers, is that even though the maximum is 127 elements, a list of
more than a few elements is hardly ever expected in practice (even more than
one element isn't actually expected: either "entire BSS" or a single LAC). It
is thus useful to log the entire list when it shows up in Paging and Handover.
