[PATCH] Cygwin: pty: Rename input/output named pipes.

- Currently, names of output pipes are "pty%d-to-master" and "pty%d-
  to-master-cyg" and names of input pipes are "pty%d-to-slave" and
  "pty%d-from-master". With this patch, these pipes are renamed to
  "pty%d-to-master-nat", "pty%d-to-master", "pty%d-from-master-nat"
  and "pty%d-from-master" respectively.
