* Include a 'demo' component that shows some of the features.
* Currently has hooks for:
- MPI_Initialized
- top, bottom
- MPI_Init_thread
- top, bottom
- MPI_Finalized
- top, bottom
- MPI_Init
- top (pre-opal_init), top (post-opal_init), error, bottom
- MPI_Finalize
- top, bottom
* Other places in ompi can 'register' to hook into any one of these places
by passing back a component structure filled with function pointers.
* Add a `MCA_BASE_COMPONENT_FLAG_REQUIRED` flag to the MCA structure that
is checked by the `hook` framework. If a required, static component has
been excluded then the `hook` framework will fail to initialize.
- See note in `opal/mca/mca.h` as to why this is checked in the `hook`
framework and not in `opal/mca/base/mca_base_component_find.c`
