gsm: add osmo_mnc_from_str(), osmo_mnc_cmp(), osmo_plmn_cmp() for 3-digit MNC
osmo_mnc_from_str() preserves leading zeros in the string and is useful for
VTY config parsing (osmo-bsc, osmo-msc, osmo-sgsn, osmo-pcu).
osmo_{plmn,mnc}_cmp() takes care of the slight intricacy of ignoring the 3-digit flag
if the MNC is anyway >99. Will be used by osmo-sgsn.git and osmo-bsc.git. (All
current users just care about identical MNC, but a proper cmp doesn't hurt.)
