[PATCH v4 0/8] MR717: Implement application hives in the registry
Initial implementation for registry application hives, this is a step forward to get Visual Studio to run. :-) -- v4: server: save app hive into it's file when closing handle. server/registry: pass file name instead of file handle to server. kernelbase: Implement RegLoadAppKey. https://gitlab.winehq.org/wine/wine/-/merge_requests/717

I could pass the flags, but I'm not entirely sure if they are the same flags, obviously some flags should not be supported by NtLoadKey2, like the LOAD_APP_KEY flag as it needs an extra parameter for returning the loaded key. according to some unofficial documentation, the only valid flags are REG_NO_LAZY_FLUSH and no flags, adding support for REG_NO_LAZY_FLUSH, should be all that is needed Since it's an undocumented function, it isn't used by many applications, so maybe we can ignore flags and get away with it for now
