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. Change-Id: I9b2106805422f96c5cc96ebb9178451355582df3
