dropped. Hence,  removing catamount timer support.
openmpi-release.sh: update for git

Also add consistent indenting to make the loop easier to read.
Cleanup some cruft resulting from the move of the btl's to opal. We had created the ability to delay modex operations, which included a need to delay retrieving hostname info for remote procs. This allowed us to not retrieve the modex info until first message unless required - the hostname is generally only required for debug and error messages.

Properly setup the opal_process_info structure early in the initialization procedure. Define the local hostname right at the beginning of opal_init so all parts of opal can use it. Overlay that during orte_init as the user may choose to remove fqdn and strip prefixes during that time. Setup the job_session_dir and other such info immediately when it becomes available during orte_init.
