Ralph Castain a0d5c80ce0 Add a new framework for discovering local resource information such as cpu type/model, #cpus, available physical memory, etc. Two initial components (darwin and linux) are provided. This is needed to support bootstrap operations where daemons are started at node boot, and applications where initial knowledge of cpu identification is needed to guide framework component selection.
Add orte configuration option to control the use of the framework in the system. Although the code will build, it will not be active unless configured with --enable-bootstrap.

If bootstrap is enabled and the new opal_sysinfo framework can successfully determine the cpu model, pass that info to the application as an MCA param to support some work at Sun.

Also, have daemons report back the resources they find to guide process mapping in bootstrap operations (i.e., where the daemon starts at node boot as opposed to being launched at application start).

Adjust some platform files to enable these capabilities.

This commit was SVN r22244.
