Andre Puschmann c3441046c9 simplify RLC buffer status query procedures 
- 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

* minor fix

* Cleaned up code and fixed issue with the update_allocation function

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.
