Module Name:    src
Committed By:   jonathan

Modified Files:
        src/sys/kern: uipc_socket2.c

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@localhost); thanks for 
catching it!

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