prte.c: a prefix of "/" is ok

It's not an error if the prefix ends up being a plain "/". More
specifically, if we strip off all trailing "/" characters from the
prefix and end up with an empty string, then the prefix is just "/".

Protect against a NULL prefix being added to the app's attributes.

Protect against a double-/ in the prted cmd path in the ssh
launch component.

Fix add-hostfile and add-host operations

When in a managed allocation, allow addition of nodes
provided that either (a) all the nodes in the managed
portion of the allocation have the same #slots in them
so we can infer how many are in the new nodes, or (b)
the user specifies the #slots for the new nodes.

Check node names as well as aliases for match.

Add a new ras component to simulate a managed allocation.

Use global PRRTE event base for sigchld callback

Even when we utilize multiple odls progress threads
to locally fork/exec procs, we have to direct the
waitpid callback to the global event base to ensure
that all servicing of sigchld returns happens in a
thread-safe environment.

Remove the unused event base priorities as an
unnecessary distraction.
