gsm48_ra_id_by_bts(): struct gsm48_ra_id* instead of buf
Move from using deprecated gsm48_construct_ra(), which uses a buf, to
gsm48_encode_ra(), which uses a gsm48_ra_id argument. Pass struct gsm48_ra_id
around instead of a buf.
struct gsm48_ra_id is the "encoded" representation of the bytes in a typical
MCC-MNC-LAC-RAC (04.08 Routing Area Id IE, 3GPP TS 24.008 ยง 10.5.5.15). Using
the struct spares using magic numbers for byte offsets.
In the process, fix a sanitizer warning for unaligned access by using memcpy()
instead of pointer assignment:
osmo-bsc/src/libbsc/abis_nm.c:2857:27: runtime error: store to misaligned address 0x7ffe8e0d6695 for type 'uint16_t', which requires 2 byte alignment
Note that (besides removing a now unnecessary cast) the gsm0408_test and
abis_test tests of RAI / CGI encoding remain stable, which indicates that the
new code is still correct.
