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

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

enb: set maximum allowed TTI difference between PHY and Stack TTI clocks for ZMQ
...
this fixes the issue where PHY and MAC threads, and the processing
of events therein, are drifting apart too much.
This patch effectivly enforces a strong wait on the PHY if the
stack thread is too slow in processing its tasks.
For RF hardware the default is still 8192 TTIs, for ZMQ 1 TTI is used.

enb_mac: pre-allocate UE object for quicker PRACH/RAR handling

we've seen long delays in handling PRACH on low-power devices

in creating the UE object on the fly during PRACH handling.
This patch pre-allocates one UE object that is then used
during the PRACH.
