Changes on srsENB mutexing logic to fix general race condition and deadlock issues (#229) 
* fixed some issues with the UL scheduling

* Hack to fix UL scheduler

* minor fix

* Cleaned up code and fixed issue with the update_allocation function

* fixed the console printing in the enb

* log/console fix

* fixed the log print

* added a normalization factor

* RLC: entity uses dynamic instances. Simplified stop/reset/reestablish procedure. Added non-blocking interface

* Limit decimals in metrics stdout

* Changed mutexes to rwlock in RLC/RRC/MAC/PDCP to fix race conditions when removing users

* Fix deadlock bug for MIMO

* Remove headers

* Fix missing unlock causing overflows

* Do not decrease CQI when PUCCH (this is a temporal fix, requires to reduce the maximum MCS)

* Fix mutex unlock in worker

* Configurable RLC tx buffer. Default to 512 for enodeb

* Check NULL SDU in write_sdu()

* Protect RLC objects and tx_queue from being destroyed while using it

* Remove superfluous code

* Disable SIB logging

* Fix block_queue for enb

Andre Puschmann 7ca0988ea3 refactor RLC to use RAT-agnostic config 7 years ago
Andre Puschmann 8dbabb2834 rework bearer/LCID handling 
This is a larger patch that reworks the LCID handling throughout the
code.

- It first moves the RB/LCID mapping out of common.h into the RRC object
  because different RATs may have different mappings.
- It adds a interface to RRC that other objects like RLC/PDCP/etc. may
  use to get the bearer name of a specific LCID.
- The patch also introduces a PDCP config class.
