********
This patch fixes three issues with rpc.lockd dealing with replies to message
passing RPCs, requests from hosts with multiple IP addresses and grant messages
issued to down clients.
Message passing RPC replies would be sent to the IP address of the lock's 
"caller_name" field instead of to the call message's source.  This patch fixes
that problem.  This patch also addresses problems handling requests from clients
with multiple IP addresses for its hostname.  This patch further addresses the
situation when granted messages are sent to a down server.  Finally, this patch
uses mkstemp for temporary file creation.
