* sysdeps/mach/hurd/getsockname.c (getsockname): Set *LEN to the 
actual length if the adress length is smaller than the input 
value.  Change type of *LEN paramater to socklen_t. 
* sysdeps/mach/hurd/getpeername.c (getpeername): Likewise. 
* sysdeps/mach/hurd/accept.c (accept): Likewise. 
* sysdeps/mach/hurd/recvfrom.c (recvfrom): Likewise. 
* sysdeps/mach/hurd/sendto.c (sendto): Change type of ADDR_LEN 
paramater to socklen_t.
