Pull up following revision(s) (requested by taca in ticket #132):
        sys/kern/uipc_usrreq.c: revision 1.172
Make behavior of getsockname(2) (and maybe getpeername(2)) as the same as
NetBSD 6.1_STABLE and other operating system (OS X 10.9.5).
* sa_len of sockaddr_un strucrure is always set to sizeof(sun_path).
* pathname stored in sun_path is alwasys '\0' terminated (except length
  of sun_path is sizeof(sun_path)?).
Should be fix PR kern/49247, runtime problem of lmtp service of dovecot2 on
NetBSD current and NetBSD 7.0_BETA.
