Bring in the remote launch changes. This still isn't fully functional, but impacted a few other places that were worth fixing.

Просмотр исходного кода 
1. Added a new function to launch head node processes on remote nodes.

2. Added new tool "orteprobe" that checks to see if a daemon is running on a node. If so, it reports the contact info back to the requestor. If not, it will (eventually - but not now) fork/exec a daemon on the node, report the contact info back to requestor, and then die.

3. Modified orted to handle universe name parameters, and added separate command line flags for debugging the daemon and saving daemon debugging output in a file. The "debug" flag now turns on the runtime debug info instead of the daemon debug - thus, you can now just get daemon debug info if you like.

4. Fix the dps to handle zero length strings correctly.

5. Modify the fork and rsh launchers to pass required environmental variables to the daemons and processes

6. Pulled the redirection of stdin/stdout/stderr for the daemon out of orted and put it into the daemon_init function to simplify orted logic.

7. Modified sys_info to correctly deal with passed mca param

8. Modified univ_info to parse incoming universe location information.
