Aurelien Bouteiller ccc8aa5784 Fix a segfault caused by making copies of the pointer to an array that is realloced meanwhile. The base pointer can change its address while the copy still tries to access pages that are not ours anymore.

As a safeguard, good coding style should never access directly opal_pointer_array_t->addr or opal_value_array_t->bytes_array. I found another instance of the same bug somewhere else and will commit a separate patch for it. 

This commit fixes ticket #1858 and solves user case http://www.open-mpi.org/community/lists/devel/2009/03/5731.php .

Shift the daemon collective operation to the ODLS framework. Ensure we track the collectives per job to avoid race conditions. Take advantage of the new capabilities of the routed framework to define aggregating trees for the daemon collective, and to track which daemons are participating to handle the case of sparse participation.
