Andre Puschmann dadff1a947 pdu: default initialize pdu members with MAC log 
MAC PDUs are default logged using the MAC log. So this gives
hex prints, etc. without having to manually set the logger for each
PDU.

Andre Puschmann fcf481b83e pdu: add check when unpacking MAC PDUs to not read beyond PDU length

case where the payload was read beyond the PDU length, as has been
seen with a malformed RAR PDU.

Andre Puschmann 78b07daf3b pcap: make public interfaces thread-safe and handle fopen returning nullptr 
the previous patch only introduced a thread-safe queue between
PHY workers (writers) and PCAP writer thread (consumer).

However, it is also required to protect the ctor (and close()) to
prevent corrupted PCAP files.

The patch also correctly handles the case where the PCAP couldn't
be openend for writing and doesn't start the thread.
