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.

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.
