Robert Schmidt b6d466d772 FlexRAN: reimplement timers without ITTI 
The timer code used to trigger periodic statistics message sending used
ITTI. Together with a high frequency reporting (e.g. 1ms), this resulted
in high CPU usage. This commit reimplements this:
* using a thread that is synchronized to the RU (if there is no MAC, we
  assume there is no RU generating a tick so we create the tick source
  ourselves)
* no RB trees but plain arrays
* smaller interface for users
* slight user interface changes
* remove stopped timer state: such timer might be simply removed
* remove one-shot timers

Robert Schmidt 7415d08138 FlexRAN: Simplify stats request handling 
* only set up timer for sending requests
* simplify interface for timer setup
* on timer expiry, do not pass through stats request function but
  directly send the reply
* Remove whatever report structure and use stats request directly for
  inferring the data to send

Robert Schmidt 62b89f828a FlexRAN: Circumvent different RRC/MAC layer user ID sorting 
* RRC and MAC might sort users differently
* therefore, we have to "reverse lookup" the MAC ID from the RNTI when filling
  user info
* For this purpose, add RAN API function flexran_get_mac_ue_id_rnti()

Robert Schmidt 1fc631e2a4 RAN API RRC part: Change interface to RNTI, change flexran_get_aperiodic_cqi_rep_mode() 
* the RAN API RRC part now takes rnti and does not look it up in the MAC every
  time again
* the function flexran_get_aperiodic_cqi_rep_mode() has been changed to return
  a proper protobuf variable, not OAI typedef

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
