Joshua Hursey c10bbfded6 ompi/hook: Add the hook/license framework ... * 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` Signed-off-by: Joshua Hursey <jhursey@us.ibm.com>		2017-02-27 12:05:53 -05:00
