[PATCH 2/9] [v2] wsdapi/tests: Add test for Publish

[Owen Rudge]

Initial test for the IWSDiscoveryPublisher::Publish function. Further 
tests will follow when this is committed.

Due to the nature of the test, this patch includes a fair bit of code 
that will also be used by the Wine implementation of this function 
(mainly the functions join_multicast_group, set_send_interface, 
resolve_address, and with some minor modifications start_listening and 
start_listening_on_all_addresses). Would it be acceptable to store this 
common code in a header (or .c) file in the top-level wsdapi directory 
and #include "../network_common.h" from the tests to avoid duplication, 
or is the approach I've taken in this patch of duplicating the code best?
