     Allow openTempFile to retry when it hits a directory (#4968).

     Windows returns an EACCES error instead of EEXIST when a call to
 `open`
     fails due to an existing directory, so add a special case for this
     situation.

     Refactor findTempName: factor out file creation.

     Add openNewFile function, which creates a new file and returns a file
     descriptor for it.
