[PATCH v3 0/2] MR192: ws2_32: Allow getsockname after AcceptEx

[DavidCurtiss (＠DavidCurtiss)]

.NET 6's HTTP/Socket code queries this. Winsock allows getsockname
on the AcceptEx AcceptSocket, but only if SO_UPDATE_ACCEPT_CONTEXT
is set.

Can you please make this a single, self-contained commit, instead of 
fixing it up with a separate commit? We don't squash anything when 
merging, and we want to have a sensible commit history.
