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

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.

Francisco Paisana eafc003671 Altered the way the generation of the scheduling decision for a given
TTI is made. Instead of generating one CC in each dl_sched()/ul_sched()
call, all CC decisions are generated at once. This avoids race
conditions with calls from the RRC to the MAC to configure UEs.
