fix creation of malformed RLC AM status PDU
...
the issue was caused by an unneeded length check during the
assembly of the status PDU. This length check caused an too early
break from the while-loop that adds all missing SNs to the status PDU
leaving the PDU struct in an invalid state where ack_sn was equal to
one of the NACK_SNs.
The fix is to simply remove the length check during the generation to
fully generate the status PDU. If, for whatever reason, MAC provides
a too small grant to fully fit the status PDU, the PDU will not be
generated, i.e. the calling function checks the return value and does
not pass the (then too big PDU) down the stack.

created a asn1 utils with helper functions and types related to the asn1. These types/functions will help isolate the rrc_asn1 lib from most of the layers, reducing this way the compile times, and leading to better isolation. This will also make the transition to NR smoother. I removed the asn1 types from the NAS and USIM interface so far.

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.
