Brian Barrett 566a050c23 Next step in the project split, mainly source code re-arranging
- move files out of toplevel include/ and etc/, moving it into the
    sub-projects
  - rather than including config headers with <project>/include, 
    have them as <project>
  - require all headers to be included with a project prefix, with
    the exception of the config headers ({opal,orte,ompi}_config.h
    mpi.h, and mpif.h)

* These are the component function prototypes. These function pointers
* go into the component structure. These functions (query() and finalize()
* are called during topo_base_select(). Each component is query() ied
* and subsequently, all the unselected components are finalize() 'ed
* so that any *stuff* they did during query() can be undone. By
* similar logic, finalize() is also called on the component which
* was selected when the communicator is being destroyed.
*
* So, to sum it up, every component carries 4 functions:
* 1. open() - called during MPI_INIT
* 2. close() - called during MPI_FINALIZE
* 3. query() - called to select a particular component
* 4. finalize() - called when actions taken during query have
* to be undone
