Log Message:
Pull up following revision(s) (requested by riastradh in ticket #1833):

        sys/compat/netbsd32/netbsd32_netbsd.c: revision 1.232
        sys/compat/netbsd32/netbsd32_socket.c: revision 1.56
        sys/compat/netbsd32/netbsd32_conv.h: revision 1.45
        sys/compat/netbsd32/netbsd32_fs.c: revision 1.92
        sys/compat/netbsd32/netbsd32.h: revision 1.137

The read/write/send/recv system calls return ssize_t because -1 is
returned on error.  Therefore we must restrict the lengths of any
buffers to NETBSD32_SSIZE_MAX with compat32 to avoid garbage return
values.

Fixes ATF lib/libc/sys/t_write:write_err.
