Change subject: PCU: add IPv6 support for SNS
......................................................................
PCU: add IPv6 support for SNS
With PCUIF 10 the remote can be IPv4 or IPv6.
Add all missing parts including SNS IPv6 elements,
the support to omit IPv4 elements and a PCU_Tests_SNSv6.cfg
configuration to run all tests with IPv6
