[PATCH v15 1/6] ntdll: separate env for windows applications (WINENV) from env for wine processes (NIXENV) WINENV is typically limited to 32767 WCHAR, the host environment where wine processes are running can be much larger. Keeping the two envs separate enables a more granula handling of envvars. (see also MR!5231, MR!6140, bug #56941)
