  Stop sending IPv6 link-local scope-ids in SIP messages
  
  The idea behind the patch listed below was used, but in a more targeted manner.
  There are now address stringification functions for addresses that are meant to
  be sent to a remote party. Link-local scope-ids only make sense on the machine
  from which they originate and so are stripped in the new functions.
  
  There is also a host sanitization function added to chan_sip which is used
  for when peer and dialog tohost fields or sip_registry hostnames are used to
  craft a SIP message.
  
  Also added are some basic unit tests for netsock2 address parsing.
