We only need to do the negative to positive conversion on values that are
passed out through the API's, e.g. libcpg.  corosync/openais can continue
to use the nodeid's as they are.  So, we don't need to break
compatibility.

The alternative is for programs to put wrappers around things like libcpg
to do the nodeid conversion.

Current programs assume non-negative nodeids.  The advantage of making
them positive is that the programs no longer break.
