* misc fixes: setsockopt() replaces Setsocksize() in certain cases and
  Setsocksize() fix to len parameter. Patch is courtesy by Vincent Bernat


* fix, nfprobe plugin: improved handling of unsuccessful send()s to prevent
  file descriptors depletion and log cause of failure. Patch is courtesy by
  Mike Jager.


* fix, networks_file: feature has been hooked up to the 'fallback' setting
  of [pm|u|sf|nf]acctd_net.


* fix, nfacctd: gracefully handling the case of NetFlow v9/IPFIX flowset
  length of zero; unproper handling of the condition was causing nfacctd
  to infinite loop over the packet; patch is courtesy by Mike Jager.


* GeoIP lookups: added a quick-start guide to document the feature
* Docs: updated AUTHORS information


* Docs updated


* Rolled version counters


* sfacctd: improved support for L2 accounting, ethernet length is now being
  committed as packet length; this information gets replaced by any length
  information will come from upper layers, if any is reported. Thanks to
  Daniel Swarbrick for his support.


* Building sub-system: two popular configure switches --enable-threads and
  --enable-64bit are now set to true by default.


* fix, print & mongodb plugins: added missing cases for src_net and dst_net
  primitives.


* fix, SQL plugins: improved handling of fork() calls when return value is
  -1 (fork failed). Many thanks to Stefano Birmani for his valuable support
  troubleshooting the issue.


* fix, ISIS daemon: linklist functions got isis_ prefix in order to prevent
  namespace clashes with othe libraries (ie. MySQL) we link against. Thanks
  to Stefano Birmani for reporting the issue.

  Stefano Birmani for reporting the issue.


* networks_file: introduced support for (BGP) next-hop (peer_dst_ip) in
  addition to existing fields.
* networks_file: improved debug output
* networks_file: docs and examples updated


* networks_file: introducing a new networks_file_filter feature to make
  networks_file work as a filter in addition to its resolver functionality:
  if set to true net and host values not belonging to defined networks are
  zeroed out. See UPGRADE document for backward compatibility notice titled
  "networks_file & host aggregation primitives".


* tee plugin: initial implementation of multiple receivers


* tee plugin: initial implementation of multiple receivers (cont.d)


* tee plugin: implemented multiple receivers per plugin and the list of
  receivers is reloadable at runtime. Documentation and examples updated.


* print, memory plugins: introducing selection of separator for CSV outputs
  via a new print_output_separator configuration directive. Default comma
  separator is generally fine except for typical BGP AS-SET representation.
