5fde3e0e00 Move the resilient orte errmgr code into a seperate errmgr for now while it's
still unstable. Reverted errmgr modules back to the original errmgr (with the
updates since the resilient code was brought into the trunk).

e1ba09ad51 Add a resilience to ORTE. Allows the runtime to continue after a process (or
ORTED) failure. Note that more work will be necessary to allow the MPI layer to
take advantage of this.

Per RFC:

fa3f6485d8 Make sure to define the region of time in which the migration is occurring so that the automatic recovery does not jump in the middle when we are moving processes around.

8ec85c6b8f Fixes the C/R Automatic Recovery feature when the HNP is also hosting processes locally.
I want to thank Hugo Meyer for reporting this/these bugs.

Notes:
 * Moved over a patch from the stabilization branch that makes sure we close the peer socket in the OOB TCP component fully during shutdown (after the de-registration sync). It also ensures that we free the rml_uri only after we are done communicating with the peer (in the odls_base deregister sync operation).
 * When an error is detected while delivering messages, we really want to bail out of the loop since the error manager is likely mutating the orte_local_children data structure, so it is no longer safe to iterate over in the orte_odls_base_default_deliver_message() function.
 * When the HNP is hosting processes make sure it accounts for processes that may have failed locally in the ErrMgr HNP component by decrementing the num_local_procs. This makes it match the orted ErrMgr component accounting. This is what was causing the modex to fail (the number of participants was wrong on a rolling recovery.
 * The crmig and autor features of the hnp ErrMgr component now check for the jobid from both the 'job' parameter and from the process name (since one may be there and not the other). This caused some additional error messages during startup.
 * If we fail to migrate (e.g., due to invalid node specification), print only the error message, not the error and success messages. This can be misleading.

fabd5cc153 Simplification of the ErrMgr framework by removing the 'stack'/composite functionality.
The composite functionality was becoming difficult to maintain, so we removed it for now which simplifies the framework design considerably.

Since the 'crmig' and 'autor' components were -very- similar to the 'hnp' component, this commit also merges them together. By moving the 'crmig' and 'autor' to a separate file under the 'hnp' component we are able to isolate the C/R logic to a large extent, thus being only minimally hooked into the previous 'hnp' component.

So other than some name changes, the functionality is all still in place. I will update the C/R documentation later this morning.
