Timing advance and power level indicated by MS (measurement reports)
and BTS (SI 5/6) are now stored for use at ACCH data link connection.
This is part of a set of commit to fix LAPDm to handle datalink
connection on ACCH (SAPI 3)
This is required to transfer SMS on SACCH of TCH/f or SDCCH/8 (4).

Instead of mixing together the GSM layer 1 interface and RSL interface
with the implementation of LAPD, the core function of LAPD is now
extracted from LAPDm. The core implementation is now in lapd_core.c
and lapd_core.h respectively.
The lapd_core.c implements exactly one datalink instance for one SAP.
The surrounding implementation "lapdm.c" codes/decodes the layer 2
headers and handles multiplexing and datalink instances, as well as
translates primitives from/to RSL layer.
lapd_core.c can now be used for other LAPD implementations. (ISDN/ABIS)
