Francisco Paisana b7ed8b1858 - added react method to to_state<...> transitions 
- s1 handover composite state simplified
- the eNB now starts a HO cancellation when it receives an invalid
Handover Command
- the FSM log now prints the current state when it receives an unhandled

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.

Francisco Paisana c46402c836 fix phy configuration during handover on srsenb. The function srsenb::rrc::ue::fill_scell_to_addmod_list assumes that the phy_cfg of the PCell is up-to-date, which was not the case. With this PR, the srsenb rrc updates the phy_cfg before the ho cmd is sent, but, in the case of intra-enb ho, the updates are not submitted to the phy before the reception of the crnti mac ce 4 years ago

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy 
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism
