add mutex in pdcp entity
...
write_sdu and write_pdu are not re-entrant because all functions
that deal with the counters, e.g. integrity check and generate,
must be protected because MAC threads may call them at the same time.

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

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.

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.
