[PATCH v2 1/2] server: Return STATUS_IMAGE_INVALID_NOT_MZ on create_mapping for a fake 16 bit dll.
If request ( create_mapping ) returns STATUS_IMAGE_INVALID_WIN_16 for a file, then the search fails, but STATUS_IMAGE_INVALID_NOT_MZ triggers attempt to load *.so file instead in ntdll. It allows to run 16 bin applications again.

Don't release nt_name in find_builtin_without_file for STATUS_INVALID_IMAGE_NOT_MZ and use it to try to load *.so instead of 16 bit fake dll, replace "-windows", if found in the path, with "-unix", and append ".so". -- Now Wine can't start any 16 bit app because if fails to load krnl386.exe16. To load any 16 bit dll, ntdll uses find_builtin_without_file -> open_dll_file -> NtCreateSection which makes a request ( create_mapping ) to wineserver, which in turn fails, hence nt_name of the fake dll is cleared.
