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 framework is for the selection and assignment of "op" modules
|
|
* to intrinsic MPI_Op objects. This framework is not used for
|
|
* user-defined MPI_Op objects.
|
|
*
|
|
* The main idea is to let intrinsic MPI_Ops be able to utilize
|
|
* functions from multiple op modules, based on the (datatype,
|
|
* operation) tuple. Hence, it is possible for specialized hardware
|
|
* to be utilized for datatypes and operations that are supported.
