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).
