rHGab595920de0e: revlogutils: move the NodeMap class in a dedicated nodemap module
Summary

We will introduce more nodemap related code, so it make sense to move the
existing code in that module first.

We recently gained a mercurial.utils module. Should mercurial.revlogutils become mercurial.utils.revlogutil instead?

utils is older than revlogutils, revlogutils focus on revlog related changes and his worth keeping at this.
