Andre Puschmann 58763fb714 stack: move initialization of log object into ctor
this fixes the issue when the stack is torn down if, for example,
the radio couldn't be loaded correctly. it will hence call stop() on all stack
components which are not initialzized yet, and logging therefore doesn't work.
the log object is know during contruction time and therefore can be passed
in as soon as possible.

Andre Puschmann c3441046c9 simplify RLC buffer status query procedures
- add a simple and low-overhead has_data() method to check whether

  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

Andre Puschmann 86e02921f0 fix regression in RLC base introduced during refactor causing eMBMS to fail 6 years ago
Andre Puschmann 22b4396c39 increase default tx_queue length for RLC UM and AM
- With the current default tx queue length (16 SDUs) the BSR reported by the UE
  is too low if the size of the SDU is relativly small (e.g. 100 B).
  This effectivly causes the eNB to only allocate a small grant
  to the UE and thus reduces the UL throughput for small SDUs.

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.
