bts.cpp: Fix overloading ambiguity
Fix error introduced in 1275a3f91a744e011b0dba82b09124d249c7abb5 by
    using signed 32 bit integer which is enough for Frame Number in
    GSM. Also, mark parameter constraints more explicitly:
    - add assert for expected FN values
    - don't perform computation for non-relative FN
The error was:
    bts.cpp: In member function ‘uint32_t BTS::rfn_to_fn(uint32_t)’:
    bts.cpp:554:25: error: call of overloaded ‘abs(uint32_t)’ is ambiguous
      if (abs(rfn - m_cur_rfn) > RFN_THRESHOLD) {
