  Remove old version. Getting ready for new libpcap 1.5
  Remove commas from clauses in a comma-separated list.
  Fix typo.
  Describe all NFLOG TLV types and define structures for some of them.
  Check caplen in the NFLOG TLV loop.
  Have nflog_tlv_t include only the TLV header.
  Byte-swap the T and L in TLVs as necessary when reading an NFLOG file.
  Don't support D-Bus sniffing on OS X.
  Add post-1.5.2 bug fixes.
  Tag some changes with a bug identifier.
  Add items for 1.5.1 and 1.5.2.
  Formatting tweak.
  Count *ring buffer blocks*, not *packets* to be filtered in userland.
  Add a PACKET_COUNT_IS_UNLIMITED() to test for a packet count <= 0.
  Use HAVE_TPACKET3 rather than TPACKET_V3 to test for TPACKET_V3 support.
  Fix builds on systems without TPACKET_V3.
  tweak manpages formatting
  Fix pcap_loop() with a count of 0 and TPACKET_V3.
  Discourage the use of a zero timeout.
  We can't use TPACKET_V3 in immediate mode, so fall back on TPACKET_V2.
