ws2_32: Return the full list of local IP addresses when gethostbyname() is called on the local hostname.

Don't rely on CFLocaleGetIdentifier(), whose result may not be sensible to

ddraw/d3d8/d3d9 only support a limited number of formats, but those already
limit the supported formats themselves.

This should be done by the context management these days.

Some of these formats can't even be translated by ddraw.
