Log Message:
Fix COMPAT_NETBSD32 cmsg handling:

1. alignment was wrong for > 1 message
2. macros were doing incorrect pointer comparisons, fortunately ending
   the iteration early after the fists cmsg instead of crashing.
3. don't output 32 bit ktrace records for cmsg. 32 bit programs running
   under emulation on 64 bit systems should produce 64 bit ktrace records
   so that the native ktrace can handle the records; remove extra arguments
   that are now not needed (the 32 bit msghdr).
4. output the correct type for cmsg trace records.
5. output all the cmsg records in traces instead of just the first one.

Welcome to 8.99.15 because of the argument removal.

XXX: Really all the code should be changed to use the CMSG_{FIRST,NXT}HDR
macros...
