George Bosilca 0ce76248e8 Close the file descriptors used to push or pull the data to the children. ...

Without this patch, doing spawn in a loop ended up by exhausting all
available file descriptors pretty quickly. There were about 5 file
descriptors opened per spawned process. Now the number of file
descriptors managed by the process (orted or HNP)
is a lot smaller.

This commit was SVN r19864.

base.h

Finish cleanup of stdin. Set non-stdio file descriptors to non-blocking (thanks to Jeff for catching that one). Handle writes that result in "would have blocked" errno.

iof_base_close.c

Roll in the revamped IOF subsystem. Per the devel mailing list email, this is a complete rewrite of the iof framework designed to simplify the code for maintainability, and to support features we had planned to do, but were too difficult to implement in the old code. Specifically, the new code:

iof_base_setup.h

Effectively revert the orte_output system and return to direct use of opal_output at all levels. Retain the orte_show_help subsystem to allow aggregation of show_help messages at the HNP.
