Andre Puschmann aec18a93d1 mux,bsr: refactor UL buffer status reporting 
this patch fixes the UL BSR as per TS 36.321, it includes following
main changes:

* report UL buffer state to reflect the UEs transmit buffer after
  the MAC UL PDU containing the BSR has been built.
  In other words, if the UE, for example, can transmit all outstanding
  data in an UL grant, it will not report any pending data to transmit.

* refactor MUX routines and subheader space calculation

Andre Puschmann 62e4bd9469 log_ptr: fix issue if accessing log_ptr that was reset already 
during deinit of the UE/eNB it could happen that the log_ptr
was already set to null but the stack thread was still accessing
it through log_h->info()

i've moved the old macro into a new header and used as as much
as possible. there are still places in the code where similar
macros are used but we would need to change the variable name
to replace them

RRC-PHY interface (#639) 
RRC-PHY interface refactor. Moved RRC-MAC interface to rrc_asn1_utils and created RRC-PHY interface also in rrc_asn1_utils. All ASN1 includes should be made from rrc_asn1_utils only keeping ue_interfaces clean of ASN1

Tested with different common and dedicated configurations (64QAM UL, 256QAM, CA, SRS enabled/disabled, etc)

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.
