the variable was only used inside the run_tti() function
and isn't needed elsewhere. refactor therefore.

Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes:
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.

Francisco 99f94d9a1a Bug fixes of srseNB scheduler TPC
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.
  Turns out using a time-windowed average for the SNR was a bad idea.
  If the UL grants are very sporadic, the SNR time window will never have samples
  when a TPC is encoded
- update of TPC sched test
- other fixes in accumulators lib

for the reduced sample rate operation that we use by default.

This switch allows to use the default LTE sampling rates and
configure this at run-time, not compile time.

Francisco Paisana 44a9ad76f1 avoid sched_ue dangling pointer
With the sched feature that allows scheduling in TTIs
ahead of time, there is no guarantee that when
the tti arrives to generate a sched result, the stored
raw sched_ue pointers are still valid. For this reason,
I now store the rnti and check if the rnti still exists.
