Andreas Eversberg 4b332d7d0e libosmocore/gsm: Fixed total size of gsm48_req_ref 
"__attribute ((packed))" must be defined for unions, in order to make
sure that the compiler packs unions.

Andreas Eversberg c1a91a896f gsm/sms: Rewrite of SMR process, extracted from OpenBSC 
The SMR process is used to transfer SMS TPDUs. It is now extracted from
OpenBSC. It includes a real state machine now for easier debugging.

Also it implements the TR1M and TR2M timers. The memory notification
procedure is missing, but not required for network side.

Andreas.Eversberg f1f80de007 gsm/lapdm: Fix TA and power level handling in the ACCH header 
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).

root af48bed556 Split of LAPDm into a core part and a GSM specific part 
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)

Dennis Wehrle 291e61346b sms: SMS where cropped (from VTY), concatenation of SMS where not possible 
Additionally it wasn't possible to send concatenated sms from the vty.
To send multiple sms, it is necessary to use padding bits and add a user_data_header.
Therefore the gsm_7bit_encode function was splitted to gsm_7bit_encode and gsm_septets2octets.
gsm_septets2octets: this is the old gsm_7bit_encode function + additional padding parameter

Additionally the gsm_7bit_decode function was modified to take account for the user_data_header.
With the new gsm_get_octet_len function you can get the octet length for a given septet length.

I also added several sms tests.

and export the underlying raw value_string arrays instead:
abis_nm_obj_class_names / abis_nm_adm_state_names.

This permits the caller to use get_string_value() as well as
get_value_string().
