Jeff Squyres 0629cdc2d7 Bring back the changes from /tmp/jjhursey-rmaps. Specific merge
command:

svn merge -r 7567:7663 https://svn.open-mpi.org/svn/ompi/tmp/jjhursey-rmaps .

(where "." is a trunk checkout)

The logs from this branch are much more descriptive than I will put
here (including a *really* long description from last night).  Here's
the short version:

- fixed some broken implementations in ras and rmaps
- "orterun --host ..." now works and has clearly defined semantics
  (this was the impetus for the branch and all these fixes -- LANL had
  a requirement for --host to work for 1.0)
- there is still a little bit of cleanup left to do post-1.0 (we got
  correct functionality for 1.0 -- we did not fix bad implementations
  that still "work")
  - rds/hostfile and ras/hostfile handshaking
  - singleton node segment assignments in stage1
  - remove the default hostfile (no need for it anymore with the
    localhost ras component)
  - clean up pls components to avoid duplicate ras mapping queries
  - [possible] -bynode/-byslot being specific to a single app context 

This commit was SVN r7664.
