Notes:
- This commit also eliminates the need for an available components list in use
in several frameworks. None of the code in question was making use of the
priority field of the priority component list item so these extra lists were
removed.
- Cleaned up selection code in several frameworks to sort lists using opal_list_sort.
- Cleans up the ompi/orte-info functions. Expose the functions that construct the
list of params so they can be used elsewhere.

|
* This function invokes the selection process for rte components,
|
|
* which works as follows:
|
|
*
|
|
* - If the \em rte MCA parameter is not specified, the
|
|
* selection set is all available rte components.
|
|
* - If the \em rte MCA parameter is specified, the
|
|
* selection set is just that component.
|
|
* - All components in the selection set are queried to see if
|
|
* they want to run. All components that want to run are ranked
|
|
* by their priority and the highest priority component is
|
|
* selected. All non-selected components have their "close"
|
|
* function invoked to let them know that they were not selected.
|
|
* - The selected component will have its "init" function invoked to
|
|
* let it know that it was selected.
|
|
*
|
|
* If we fall through this entire process and no component is
|
|
* selected, then return OMPI_NOT_FOUND (this is not a fatal
|
|
* error).
|
|
*
|
|
* At the end of this process, we'll either have a single
|
|
* component that is selected and initialized, or no component was
|
|
* selected. If no component was selected, subsequent invocation
|
|
* of the rte wrapper functions will return an error.
