call to freebsd32_convert_msg_in() with freebsd32_copyin_control() to
readin and convert in a single step. This makes it simpler to put all
the control messages in a single mbuf or mbuf cluster as per the
limitations imposed upon us by ip6_setpktopts().
The logic is as follows:
1. Go over the array of control messages to determine overall size
and include extra padding for proper alignment as we go.
2. Get a mbuf or mbuf cluster as needed or fail if the overall
(adjusted) size is larger than a cluster.
3. Go over the array of control messages again, but now copy them
into kernel space and into aligned offsets.
4. Update the length of the control message to take padding between
the header and the data into account (but not for padding added
between one control message and the next).
