david 02cb2931aa Fix rt_msghdr padding on NetBSD. ...

NetBSD uses a fixed 64-bit padding, unlike OS X (32-bit), and unlike
other platforms (sizeof(unsigned long)). There is an RT_ROUNDUP macro
that does the right alignment; use that when available.

Rounding to 4 bytes was breaking with IPv6 addresses, which are 28
bytes. The pointer was being advanced by 28 instead of 32. Compare to
r29739, somewhat similar.
