[PATCH v4 0/4] MR1801: secur32: schannel AcceptSecurityContext support
Adds support for AcceptSecurityContext to secur32 schannel Note: I'm not especially familiar with the secure channel API and mostly poked things until they worked. I can confirm it works well enough for [an application](https://store.steampowered.com/app/1787820/Mirror_Party/) using Microsoft's [Microsoft.Extensions.Hosting](https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.hosting) .NET api to successfully negotiate a TLS connection with curl though. -- v4: secur32: Add test for AcceptSecurityContext https://gitlab.winehq.org/wine/wine/-/merge_requests/1801
