Hello folks,

needed for some tools like 'processhacker' (via plugins-extra) and/or Win
Vista+ native wininet (attempt to prove bug 45847).

Looks pretty inconsistent. There is no pattern between Ipv4, Ipv6 and/or A/W
ExA/ExW pairs of the API recognizable here.
Some are auto-generated stubs, some are stubs, some are simply not present
(commented out). 

The Ipv4 string <-> address functions are not very hard to implement.
Wine tests for this family of functions were added some time ago via
Wine-Staging:
