opendir() and a too long path

Description

Hi/2.

opendir() assumes that a path length is enough smaller than MAXPATHLEN. So if a path length is longer than MAXPATHLEN, a stack is corrupted.

To fix this, nbuf should not be declared statically using MAXPATHLEN. Instead, it should be declared dynamically using malloc() in according to a length of 'name'.
