Andre Puschmann c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

Francisco cdf72248f3 Reimplement batch-based background object/memory pool
Main changes:
- addition of pool utilities
- The node size/alignment and batch allocation threshold are now runtime arguments
- object pool and memory pool are not anymore based on the same class.
  The object pool cannot use intrusive free list because it would overwrite the object
  memory

Port enb specific classes to use srslog (#2155)
* - Started porting the enb PHY layer to use srslog loggers.
- Updated srslog to manage the none level.

* Finished porting enb phy layer including the NR part.

* Ported MAC, GTPU, PDCP, RLC and S1AP enb classes to use srslog.

* Use new stack logger.

* Ported the enb RRC clases to use srslog.

* Remove unused log macros.

* Replace loggers in sched, sched_carrier, sched_helpers.

* Replaced loggers in sched grid.

* Replaced loggers in sched harq.

* Replaced loggers in sched ue.

* Replaced loggers in sched ue ctrl.

* Replace loggers in sched ue ctrl TPC.

* Replaced loggers in sched subclasses.

* Replaced loggers in rrc_meascfg_test

* Configure loggers in rrc_mobility_test.

* Fix compilation errors left out after the rebase.

* - Implement a custom log sink that will serve as a test spy to intercept and count the number of error and warning log entries.
- Adapt the erab_test_setup and rrc_mobility tests to use this new class and make them pass again.

* - Remove trailing new lines introduced in the rebase.
- Ported the sched_ue_cell class to srslog.

* Remove unused log member.

* Ported mac tests to srslog.

* - Removed remaining trailing newlines from log entries.

* Fix compiler errors detected in CI.

* Fix another static variable without definition passed to log lines.

* Fixed a bug in srslog::flush that would never end when the backend queue is full.

* Fetch the RRC logger instead of injecting it in the constructor.

Andre Puschmann a0e4b18507 enb_mac: pre-allocate UE object for quicker PRACH/RAR handling
we've seen long delays in handling PRACH on low-power devices
such as the RPi4. This was mainly caused by long delays
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.
