Subject: 	* ntdll.h (RtlInitCountedUnicodeString): Swap order of string
 and length 	parameters to be the same as for RtlInitEmptyUnicodeString. 
 (RtlEqualPathPrefix): New inline function. 	(RtlEqualPathSuffix): New
 inline function. 	* fhandler_disk_file.cc: Accommodate parameter order
 change of 	RtlInitEmptyUnicodeString throughout. 
 (fhandler_disk_file::link): Do path checking in unicode.  Call 
 CopyFileW instead of CopyFileA.
