This patch is another step towards a working RLC/MAC implementation. It adds:
* An initial data model with MS (gprs_rlcmac_entity) and ul_tbf.
* A UL_TBF state FSM from initial to FLOW status
* A UL_TBF assignemnt FSM, covering both 1phase and 2phase assignments.
* Triggering of UL_TBF allocation and assignment FSM when new LLC data
is pushed from upper layers.
* A scheduler generating some ctrl messages (PktResReq and UlDummyCtrlBlk)
when indicated by the network.
This patch is pushed as a WIP state since it already contains a
considerable amount of code and lots of new files, which can be
used/extended at a later point, making parallel contribution easier.
