Add option for disabling use of IP_PKTINFO

There is a small performance penalty associated with the use of the IP_PKTINFO socket
option. This adds an option Internal/ExtendedPacketInfo to disable it because there may be
cases where preventing the performance loss is more important than preventing some
discovery mishaps.

 The categorisation of tracing output is incomplete and hence most of the verbosity levels and categories are not of much use in the current release. This is an ongoing process and here we describe the target situation rather than the current situation. Currently, the most useful verbosity levels are config, fine and finest.
