* autoload.cc: Replace WNet[...]A with WNet[...]W imports. 

* dcrt0.cc (initial_env): Drop strlwr calls.  Call strcasestr instead.
	* fhandler_netdrive.cc: Throughout, convert to calling WNet UNICODE
	functions.  Use tmp_pathbuf rather than alloca.  Replace call to
	strlwr with call to RtlDowncaseUnicodeString.
