This code should not play with the internals of the msgb like this,
this code got introduced in af48bed556 and is breaking the
osmo-bts usecase of forwarding an RSL message.
Add a test case that fails without the new code. I would prefer if
we could get rid of the manipulating the msgb like this, it is prone
to errors like this one.

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)
