Rename 'bts_data' leftovers to 'bts'

Before, we used tho have a BTs object split into 2 parts, a C
gprs_rlcmac_bts struct and a C++ BTS struct, and "bts_data" naming was
used to distinguish them in variable names. Nowadays the struct is
finally combined into one, so there's no point in using this "bts_data"
terminology, we use always "bts".
