* ntdll.h: Add descriptive comments to special Rtl functions.
(STATUS_OBJECT_PATH_NOT_FOUND): Define. (STATUS_BUFFER_OVERFLOW): Define. (FILE_SUPERSEDED): Define. (FILE_OPENED): Define. (FILE_CREATED): Define. (FILE_OVERWRITTEN): Define. (FILE_EXISTS): Define. (FILE_DOES_NOT_EXIST): Define. (PIO_APC_ROUTINE): Typedef. (NtFsControlFile): Fix parameter types to use PIO_APC_ROUTINE. (NtWriteFile): Declare. (RtlInt64ToHexUnicodeString): Declare. * strfuncs.cc: Include ntdll.h. (RtlInt64ToHexUnicodeString): New function. * syscalls.cc (try_to_bin): Rewrite using native NT functions. Only try to create recycle bin after unsuccessfully trying to move file. Also try to create special files in recycle bin so that Windows Explorer isn't unnecessarily stampeded.
