Robert Schmidt 9c47c860bc FlexRAN: RCconfig_flexran(): only read necessary information 
if the FlexRAN agent is disabled, do not read all the data and skip reading
of more information

Robert Schmidt 1854826053 FlexRAN: send agent_id (aka enb_id) 2018-03-22 18:43:15 +01:00
Robert Schmidt e7a60fc992 FlexRAN: make agent_id for identification purposes, discern from mod_id 
The agent_id is a uint64 consisting of: module ID (i.e. mod_id, the several
instances of OAI at once, 16 bit), the enb_id from the configuration file (32
bit) and the cell_id from the configuration file (16 bit).

The module ID is part of the agent ID but it is easier to have it directly in
the struct.

Robert Schmidt 318e4a345e free configmodule memory when shutting down 
It is possible to restart the lte-softmodem via the FlexRAN controller. For
this to work, the end_configmodule() method needs to be called when shutting
the lte-softmodem down so that the configuration can be read again during a
restart.

Robert Schmidt 7b1afbb0bf provide stop_L1L2()/restart_L1L2() in oaisim 
the functions are meant to restart the lte-softmodem (lower layers) and are not
supported in oaisim. They are provided to make oaisim compile.

Robert Schmidt d092231181 free memory when stopping/restarting lte-softmodem 
- add function free_td() -> complements init_td() [seems to not be used, added
  for completeness]
- add function free_td8() -> undoes init_td8() [free memory of 8-bit LLR Turbo
  decoder]
- add function free_td16() -> undoes init_td16() [free memory of 16-bit LLR
  Turbo decoder]
- change function free_tdavx216() -> undoes init_tdavx216() [free memory of
  16-bit LLR Turbo decoder, AVX2 version]
- add free_lte_top() -> frees memory allocated by init_lte_top()
- change free_ul_ref_sigs() to set freed pointers to NULL
- add method free_transport() -> frees memory of ULSCH/DLSCH transport channels
- use the above functions when stopping/restarting the lte-softmodem

Robert Schmidt 3f043c7d73 FlexRAN: implement possibilty to await a configuration 
Through configuration, the lte-softmodem can be halted to await a
reconfiguration from the lte-softmodem. A mutex and condition variable are used
to implement this.

Furthermore, the dependance of lte-softmodem.c on FlexRAN has been reduced to
one include and the flexran_agent_start() call.

Robert Schmidt 8e9d9807ae lte-ru.c: fct for interface -dependant config, export more functions

  restart functionality

Robert Schmidt cdbf65f5af revise RAN API 
- when changing values RC.rrc[i]->configuration should be changed too
- then, RRC_RECONFIGURATION_REQ will pass the changed conf down until PHY
- give warnings at functions that are not implemented

- rename functions

Robert Schmidt 78dd80b086 Merge branch 'feature-68-enb-agent' into feature-merge-f68 
Try to merge feature-68-enb-agent into develop
develop should be fast-forwarded later to this branch to complete the merge
This code does not compile yet. Among other things:
- the scheduler structure needs to be reworked for FlexRAN
- the config is structured differently. The files enb_config.{c,h} from develop
  have been copied in here, the files with merge annotations are in
  enb_config.{c,h}.before_merge
- the restart needs to be restructured, since the PHY vars data structure lives
  in RC now
