realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k).
reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL).
