Log Message:
Fix potential memory leak in sbappendaddrchain():

We do an MGETHDR)() for each mbuf "packet" of the input chain, to hold
the socket address prepended to that "packet".  If those MGETHDR()s
ever failed, we would leak all the successfully-allocated mbuf
headers.  Leak noted by Yamamoto-san (yamt@NetBSD.org); thanks for catching it!

Add socketbuf invariant-checking macros to sbappendaddrchain(), and
replace a stray bcopy() with memcpy(), also as suggested by Yamamoto-san.
