1.8.x AIX support

Hi there-
   I see that the three AIX issues are being pulled up to 1.8.x.  I just tried them out and found that we also need this one:

15106

   We get a kernel panic on AIX as soon as afsd is started without 15106 applied.

   I pulled in 15106 and it compiles, but then I have another problem that is that many of the servers coredump immediately:

# /opt/openafs/libexec/openafs/vlserver
IOT/Abort trap(coredump)
# dbx /opt/openafs/libexec/openafs/vlserver core
Type 'help' for help.

Are we missing another patch as well?  Anyone have an idea what it might be?

Thanks much!
