* first step towards moving MAC timers to stack. Mac is still using its own timers. srslte::timers class can be restructured.
* moved timers out of the UE MAC
- all RLC entities are now initialized during contruction
- there is no need to check for, e.g., existance of timers, during
runtime
- there is also no need to call re-init during resume
- timers are freed in dtor
- add a simple and low-overhead has_data() method to check whether
an RLC entity has data to transmit or not
- use this method for all calls that are actually not interested
in the amount of data to send
- use the more expensive get_buffer_state() for all cases where
the actual size of the buffer is of importance
* 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
